It looks like you’ve set the “Add” to edit but the Field Editor isn’t set to edit. Try this:

I don’t want the field editor in edit mode. I want it in read with inline edit mode in case the model has records on query (on the test page I have no records just to simplify). But I want it in edit mode for new records created by the button’s action.

Is this clearer?

Ah. Yes. This is now clear. I’ll get that written up and let you know when this issue is resolved.
