Squad interface problems

Today, after setting up a squad (catmander) and going into LFG I had idiosyncratic problems moving people between subsquads and also locking the squad. Then, today, after being in a wvw squad, I couldn't leave. I had to request the other squad members to kick me.

I'm not getting any error messages coming up, it's just that the interface doesn't seem to be doing anything. I've only noticed it today, I have patched properly. It was working fine 16 hours ago when I last put up squads in my previous GW2 session.
