Space with length 0 is displayed as NULL in right click popup

Hi Rob,
is there a reason why a field entry with “Space” with length 0 is displayed as Null in the right click popup (“Keep only”-popup / “Remove”-popup)?
In my screenshot there are “Space (0)” and NULL-Values in the same column but the filter popup shows always NULL for both of them.
So sometimes I filter the wrong value.

I’ll look into it.
