My account bugged

When i log ont the browser, i go to my account, TermoNuclear, level 32, server sandycove.
When i log on the app, i go to a new account, MonoDedo(uplay name), level 1, server ?

I did changed my uplay nickname from TermoNuclear to MonoDedo, but i log with my uplay account in the browser and on the app, but the app send me to a new account.
