Edit

Saved specimen type in Registration (preparation): full functionality.
Saved name specimen type in Registration (preparation): full functionality.

Saved name: Delete button is available, delete functionality is not available, but gives back the following error (screenshot).

Delete button is available for references with registrations. Trying to delete (which realy does not any sense) produced the following error.
Question: should we omitt this button for references with registrations?
For references without registrations deletion is functioning and makes sense, see above)
