Can't add new entity in specific view

I have some views that draw from 2 databases. In some of these views I am able to go to the bottom and add a new entity for each database. In other views, I can only add a new entity for one of the databases. As far as I can tell, the only difference is that on the views where I can’t add a new entity, I have a “Group By” field selected under Rows > Levels. If I remove “Group By” the option appears again to add a new entity to the table. Why would this be?

What type of views are they (table, list, … )?

If you have a view that includes grouping, then you can create a new entity within a given group by right-clicking the group and choosing New <xyz> inside

The views are all tables. I did not realize that about the right-click- I can definitely use that as a work-around, though it’s still confusing why this happens. Brand new to Fibery, so still wrapping my head around things.

If you are displaying entities that are grouped by a field which is a required field (e.g. a workflow, or a required select/relation field) then a user needs to make a deliberate choice as to which group to create a new entity in - you can’t just create an entity that doesn’t belong to any group.
This could be why you aren’t seeing a generic + New xyz at the bottom.
I suppose we could redesign so that there is a + New xyz option for each group, but this would grow the size of the table a significant amount.
