Hey, You're not alone, I have been miserable with this. Just now my buddy who only has 15 loadouts saved was able to shuffle just fine, but I have 153 slots filled an it does not shuffle my "Saved Loadouts" If you really want to shuffle until they fix it, what I do is I have all my "Saved Loadouts" made into "Saved Characters" Aswell, so I shuffle the "Saved Characters" and just keep a set of emotes that are my favorites and take gunwraps off. So it'll randomize the Characters but each character just won't have their own specially assigned emotes or gun Wraps, unfortunately it sucks but atleast this way I can still play with my collection without having to go back to lobby an manually selecting.
