AI Translate Re-translates Referenced Entities and Overwrites Existing Manual Translations
When translating a content entity using the **AI Translate** functionality, the translation process also processes entities referenced through an **Entity Reference** field.
This can result in an already translated and manually edited referenced entity being translated again as part of the same batch process. As a result, the manually modified translation of the referenced entity can be overwritten.
## Steps to Reproduce
### 1. Create Two Content Types
Create the following two content types:
- **Test A**
- **Test B**
### 2. Configure an Entity Reference
Add an **Entity Reference** field to **Test B** that references a **Test A** node.
Example:
```text
Test B
└── Entity Reference
└── Test A
```
### 3. Create Content
Create a **Test A** node:
```text
Test A
Title: Sample Content
```
Create a **Test B** node and reference the Test A node:
```text
Test B
Title: Sample Parent Content
Referenced entity:
└── Sample Content (Test A)
```
### 4. Translate Test A
Use **AI Translate** to translate the Test A node into another language.
For example:
```text
English → Arabic
```
After the translation is created, manually edit the Arabic translation of Test A.
Example:
```text
AI-generated Arabic translation
↓
User manually modifies the translation
↓
Final manually edited Arabic translation
```
The manual changes should remain intact.
### 5. Translate Test B Using AI Translate
Now translate the Test B node using **AI Translate**.
Because Test B contains an **Entity Reference** to Test A, the translation process also identifies/processes the referenced Test A entity.
### 6. Observe the Referenced Entity
The translation batch processes Test A again even though its Arabic translation already exists and may have been manually modified.
As a result, the previously manually edited translation of Test A can be overwritten by the newly generated AI translation.
## Actual Result
When Test B is translated using **AI Translate**, the referenced Test A entity is also processed/re-translated in the same batch.
If Test A already has an existing translation that was manually edited, those manual changes can be overwritten.
Example:
```text
Test A
├── Original English content
└── Arabic translation
└── Manually edited by user
↓
Test B translated using AI Translate
↓
Test A is processed again because it is referenced by Test B
↓
Existing Arabic translation of Test A is overwritten
```
This behavior can cause previously reviewed or manually maintained translations to be reverted unexpectedly.
## Expected Result
When an entity referenced through an **Entity Reference** field already has an available translation, the translation process should **not automatically re-translate or overwrite that existing translation** as a side effect of translating the parent entity.
The existing translation, including any manual changes, should remain unchanged unless an explicit action is taken to retranslate that entity.
## Impact
This behavior can result in:
- Manual translation changes being lost.
- Previously reviewed translations being overwritten.
- Unexpected content changes in languages that were already translated.
- Translation consistency issues across related entities.
- Difficulty identifying which entity was responsible for the translation update.
**The issue is fixed by setting “Translate referenced entities” to No for the relevant AI Translate field configuration.**
From your screenshot, the important setting is:
AI Translate → Translate referenced entities → **No**
Previously, it was effectively:
**Translate referenced entities → Use default → Current default for node is Yes**
