Steps to reproduce
- Have a single instance model with a saved record
- In a different model, add a field of type Multiple link
- Specify the single instance model as one of the types of model that can be linked
- Now you can add a link to the single instance of that model when editing that field
- When doing so, click From library and select the single-instance model record
- A record picker appears showing the single record available under that single-instance model
- There is a + button at the bottom
- Click this to start creating a new record under this single instance model β it should not be possible to get to this state
Possible solutions
- Remove the + button
- Better yet, do not bring up the record picker at all when selecting the record of a single instance model when adding links to a field
