Can you not get back in to the RO and remove this additional field?
This looks a missed check of dependent fields before allowing the deletion of the field. I would report this to support as a bug.
Potential workarounds so you can edit the RO:
- Try re-adding the field with the same name and data type. This may allow you to edit the SR and remove the additional field
- Try saving it to disk in a .rof file, edit it and remove the additional field, then import.
Thank you very much for your response
I have edited it directly in the database. Now everything works fine.
I will report it as a bug to the support.
