Listings won’t sort by newest date correctly

Level 1
I don’t know if it’s just me but I’ve been experiencing an annoying issue. Whenever I search for items I like to start looking by newest date listed. However even after sorting by date the listings are still mixed up. Newest is not on top, the listings are mixed and won’t sort, some are days or even months in the past still on top. It’s pretty annoying. Is there a fix for this?
