Club Tag not appearing after summoner name change

So I have changed my in-game nickname and now I can't put any of my club tags on my account. I think it might be because the server doesn't recognize my new name yet? Can I please get help sorting this problem out? My NA account name is "JipSa" now which was originally "illumina96" if you need this info.

I want to be able to play with my new club tag ._. [sg-janna]
