Stuck on choosing summoner name

Hello, I have a problem with selecting my new name after account transfer from EUNE to EUW, when i get to choose my desired name it gives the check mark that the name is free and its good to go, but when i pres "Start Now" this appears --> "Name currently unavailable. Enter a new name and try again" I entered many many names who were free aswell but still the same message comes. Please help me with that or set me an default name or whatever so i can play. Name of the account is AlwaysMadeIt in EUW currently. I would aprecciate if someone helps. Also to say I restarted the game and my computer a few times, I also uninstalled the game after that and installed it again, but the same problem appears
