Favourites disappearing from steam account (Counter Strike Source)

Does anyone else have this weird problem where you can’t see any favourites if you access the list from within counter strike source?

It's really annoying, it never used to do it but it means I have to close CS:S everytime I want to go to another server. If anyone knows a fix I'd really appreciate it
