Enable translation synchronization on fields that get created when enabling bee on a content type

I am working on multilingual site and am trying to use bee to add booking and availability management to a content type. So I enabled daily bookings on that content type and created 1 unit for a content item of that type.

However, when editing this node in another language, the bee details form element still shows 0 units being created for this node. Looking at the storage level, the target-id of the unit is indeed only stored under the language code it was edited in, not in language neutral, nor was it distributed over the other languages.

Not sure how to solve this, but with some hints I will write a patch.
