Appsheet stopped handling null groupings in UI

I have a view in desktop mode that breaks down by management heirarchy. Until recently, if a manager was not present (null), it would still allow the manager records “beneath” that grouping layer to show up. Now it excludes all records under the null layer. I believe this to be a major bug. Please see screenshot:

Even if I search for a record I know should be under the “null” group layer, it returns no results.

It is worth noting this malfunction only occurs in Desktop Mode.
