Duplicate field and Inline entity form

When i have 2 fields of the same field base (lets call it field_mycustom) inside different entities and they are referenced with inline entity form the function that field is disable on both fields but others work.

both entites have a different dependent field (selectlist) which work generelly but the field which is now twice at the form will wether hide or show up when the dependent field gets triggered

for testing purposes i renamed the field to field_mycustom2 (not the field label, i created a new field base) from the same type (text). now conditions work inside the the referenced entity and the top level entity. if i now add the field_mycustom again to the secondary entity only the condition for the field field_mycustom still works but the other not
