<p>Drupal throws an exception on saving Custom recurrence with Sierra widget.<br>
InvalidArgumentException: Failed to parse RFC string, line is not starting with a property name followed by ":" in RRule\RSet->__construct() (line 77 of /vendor/rlanvin/php-rrule/src/RSet.php).</p>
<p>Sierra widget is looking for "RRULE:" prefix in RRULE field. </p>
<p>it's caused by<br>
// Preserve non-RRULE components from original string.<br>
$originalString = $form_state->getValue('original_string');<br>
$rset = new RSet($originalString);</p>
<p>I changed Alpha to Sierra and date was already stored in Alpha format.</p>
