[تم الحل] Different domain per language

Background of the issue:
I have three languages on my site and I want to set different domains for each language. The English language should be set to الرابط المخفي, German to الرابط المخفي, and Hebrew to الرابط المخفي. I tried setting this up under 'Language URL format' in WPML by selecting 'A different domain per language' and adding my domains.

Symptoms:
When I hit save, the '/de' is removed from the German domain.

Questions:
Why is the '/de' being removed from the German domain when I save the settings?
