[تم الحل] ACF Repeater Field not pulling in translation on some fields

Background of the issue:
I am trying to resolve an issue with the ACF Repeater Field not pulling in translations on some fields. I have recorded a screen recording to show the issue here: الرابط المخفي. The issue can be seen on this page: الرابط المخفي. I expected the timeline headings to be in German as their translations have been completed in the WPML settings.

Symptoms:
The 4 x headings appear in English rather than German.

Questions:
What might be causing the ACF Repeater Field not to pull in translations on some fields?
Is there a way to resolve this issue?
