DBLOOKUP - Regression BUG or am I mistaken

I have always used DBLookup to retrieve a list of values from Column n based on key(col 1).

My problem is:

If column n is also categorized then it only returns the first value and not all the values in the column.

If column n is NOT categorized(just sorted), then I get a list.

AM I WRONG or is this a BUG?
