Help on Fc Mobile leagues

I need help with my leagues, so I was in a league and then I left it, and well I was waiting the 24 hours time. I decided to go look for a new league to join but when I logged of and logged on back, somehow I was in that league, it is like a phantom league, error 30000 and some other errors when I try to access the rewards and other pages. Please help. I already tried basic troubleshooting like restarting and deleting and reinstalling. Nothing worked.
