After adding/removing type restrictions of one metadata element several times, not all assigned type restrictions are displayed anymore.
I've attached screenshots:
fail1: Shows that "record source" element is associated with object types "Work, Variant, Manifestation"
fail2: Shows that only "Work" is displayed as type restriction. Variant and Manifestation are assigned, but not displayed anymore.
I already deleted and re-created this metadata element, because before that no type restrictions at all were displayed anymore
Happy to help debugging this!
