To recreate: 1. Create multiple Record overlay rules with Source, z39.50, TAG, protect, skip, skip, skip, skip. 2. Create Record overlay rule Source, *, 942, Protect, skip, skip, skip, skip. 3. Find a bib record and make sure it contains a 942 with selected item type. 4. Replace record via z39.50 (using the basic editor) 5. Edit the bib and change the protected tags in the overlay rules for z39.50. 5. Attempt to save the record. If 942 is a required field, you must select the item type. If that happens, select an alternate item type. The record will save and restore the tags protected through the z39.50 overlay rules. But the record will also save the alternate item type and not protect/restore the 942 tag to the previous item type. The asterisk should protect the 942 tag regardless of the cataloging process.
I believe this is a duplicate to Bug 33268 - Overlay rules don't work correctly when source is set to * It was pushed only pretty recently, so not available in 22.11, but if you avoid * for now you can make it work at least until properly fixed. *** This bug has been marked as a duplicate of bug 33268 ***
