[تم الحل] Our homepage has been translated but does not display the translation

Background of the issue:
In our test environment of the website (Isoplanner.app) الرابط المخفي, we are experiencing an issue with the translation of the homepage. It has been automatically translated into Dutch and German from the default language "English". In the back-end, we can see all the translations into both Dutch and German when we open the page using the "Classic Editor" (Divi Builder) as well as the "Advanced Translation Editor". We have already cleared the WPML Cache in "WPML > Support > Troubleshooting" and performed other related actions.

What could be the cause of this problem, and can you help us with it?
