Alpha client bug

In champ select it's usually laggy. I've played a bit with the client on the pbe as well and during champ select I always edit my masteries but with the new client it constantly won't let me edit the page at all. I can't rename the page, clear it, use or refund points, or even switch pages. I only have one mastery page usually but I made a few on the pbe because of this bug. I'll be testing more on the pbe server with the client because I don't care about winning as much on there. Thank you for taking the time to read this and I hope you have a wonderful day/night.
