When I try to use the Filter from the Attribute Table -> Options and select Unique none of my choices get populated. Is there some box I need to check for this to work? See pic for description.
do you see any errors in your browsers web console?
No I do not have any errors
So you are saying that you do not see any error in the web console when you using your browser's developer tools (F12)
There is warning: Filter#buildByExpr() method is deprecated, please use Filter#build() instead.
