Can't post on PBE boards because my username is the same as NA boards.

I was able to make one post. After I made the post, the username posting shows up as "null" and I was never able to post again (it tells me "login to comment")

Here's the thread with the null username:

http://boards.pbe.leagueoflegends.com/en/c/general-pbe-feedback/eIEQj4bg-how-am-i-supposed-to-buy-runes-i-was-only-given-1-ip

My profile doesn't exist:

http://boards.pbe.leagueoflegends.com/en/player/pbe/That%20Evelynn

Where it shows me logged in on the top right, it's using my NA summoner icon instead of my PBE one:

Direct link to icon shows the same:

And I can't purchase a name change because my PBE account was given 1k RP and no IP (well, it gave me one... ONE.... lmao)
