My Regexmatch isn't working for one specific row

My formula should be looking through the green table to identify any rows that match the yellow heading of either nurse, addiction professional, etc. Then if it finds a match it should be coming back with a joined array of all of the matches and inserting them in the cell.

Green Table 1Green Table 2

Yellow Table

For the yellow table I am using the formula:

=IFNA(IF(REGEXMATCH(QUERY(CoveredP, "SELECT G where E contains '"&E$1&"'"),$D2), JOIN(", ",QUERY(CoveredP, "SELECT C where E contains '"&E$1&"'")), "No"),"No")

where &E$1& focusing on the E from E1 changes to F, G, etc. as we move horizontally,
and where $D2, focusing on the 2 from D2 changes to 3, 4, 5 etc., as we move vertically.

Any ideas?
