age filter not working in horse search

basically what the title says.
i did a search and included age as a parameter. specifically; age: exactly 0

yet i got ALL horses of any age that fit the other search parameters (black, arabian, bred by me) and not just 0 year olds.

That's happened to me too. Plus some of the parameters (like color or confo) disappear when I go to the next page of search results, so it'll go from like 7 pages of results to 20 because suddenly it's only searching one parameter of the 2 or 3 I entered. It's really annoying.
