[HR] Horse pets filter in gallery does not work

When I use the gallery filters:

1. Category: Household
2. Pets: Horses
3. And Sort By: Most Popular (but it also is broken in the other sort by options)

then 0 horses of the gallery appear, which is impossibly the correct outcome, given there are thousands of horses in the gallery. I can find horses only when I use a hashtag horse, but not with the filters anymore. The filters also always show nearly only basegame items when sorting by Most Popular, even when i picked a certain pack or several, but that issue has been raised already a year ago or longer, just mentioning it in case it has something to do with this current issue too.

The same problem happens with dogs, cats and "with pets" too.
