Problem:
On the post edit screen repeatable field groups are not shown, and instead there appears a warning about the WPML translation mode and post relationships.

Solution:
Although the message refers to post relationships it is applicable here because repeatable field groups are implemented via post relationships.

So the advice from the warning—that the WPML translation mode for the post type needs to be set to "Translatable - use translation if available" needs to be followed.
