Custom Filtering the Description Field

I am having problems performing any filtering on the Description column in the Units page. The only filter that seems to work is selecting the [Blanks] category - all other filtering including any custom filter or individual filter does not change the view.

FORUM POST UPDATE - as of AyaNova 4.2, the Unit Description field in the Units grid is now filterable including using a Custom filter.
For example:

on the Description column select the (Custom) filter
Select Contains
Enter in a text word that is in a number of the unit’s Description fields
You will see that the grid is filtered to show only unit records where the word you entered is a text entered in the Description field in a unit’s entry screen

See the forum post for a list of new and fixed issues in AyaNova 4.2.0.0 in the Known Issues & Updates section
