to reproduce use https://development.sinopia.io/editor/ld4p:RT:bf2:Monograph:Work:Un-nested
- Content field is required, so if you enter nothing and try to save, you are warned, as expected

- select a value from dropdown. now the "Required" message and red styling disappear, also as expected

- now remove the value you entered

- try to save again, and save is successful. instead, you should be warned that the field is empty
NOTE: this is a bug only with lookups, and only when you select a value from the lookup (rather than entering a "new literal")
