Monsters with more Advanced Types are not Appearing in the Monster Compendium Search

I'm trying to filter my compendium search to find "fiends" with the type of "devil," and I can only currently filter by fiends.  This means that many of the monsters with type Fiend (devil) or Fiend (demon) or any of the other special fiends are not even showing up.  Is there a way to just show any creature with the "fiend" type or search for specific creatures like different devils or demons? (I'm only seeing the option to filter by creature type "fiend." (Which, again, doesn't show all of my fiend creatures.)

Is this an in-game filter? And for the D&D compendium?

The is the "Tools" section on the home page. If you go into "compendium" and "monsters" and search by different monster types.

I agree, that is not as advanced as the in-game compendium filters. I'd suggest filing a  Help Center Request , so that the disparity will at least have a ticket addressed to it, but I'm not sure how high it is on their radar.
