I did find a fix which is necessary to support the UPPER (and other
functions of this type) if a space is between UPPER (or whatever MIN, MAX,
etc.) and the open parenthesis like this:

My Filter := 'UPPER ( mycol ) = ...

Make the fix below:

IB_Parse.pas line 6106

tmpPos := getLitsRoundSafePos( ')', AStr, EndPos + 2 );
if tmpPos > 0 then
begin
EndPos := tmpPos + 1; // Add the + 1 here.
Result := true;
end;

Hope this helps,
