A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
The problem is that FILTER does not work with wildcards.
Because of that, FILTER(LBL!$B:$B,"*Indepen*") returns only a single #VALUE!, and hence the count is 1.
Change the formula to
=COUNTA(UNIQUE(FILTER(LBL!$B:$B,ISNUMBER(SEARCH("Indepen",LBL!$B:$B)))))
