[Geschlossen] JetEngine Radio Field Value Not Showing in WPML String Translation

Background of the issue:
I am trying to translate a JetEngine radio field named soort_item in a Custom Post Type called Evenementen using WPML. I set soort_item as translatable in WPML → Settings → Custom Fields Translation.

Symptoms:
The field-soort_item value is not available for translation in WPML → String Translation. The label of the radio field is translatable, but the selected value is not.

Questions:
How can I make sure WPML detects and allows translations for JetEngine radio field values?
Is there an additional setting or workaround needed to register field-soort_item for translation?
