Can't choose my runepages

I'm unable to use my second runepage since i bought a 4th runepage. Everytime i want to choose it, it swaps instantly to my third page and then the second page has the same name and stats like the third one. It was fine at the old client but now i can't use it anymore because i have to use the new client. i bought a 4th runepage for 6300 (which is pretty much for me) but i can still use only 3. I want my EP back.
