I have the same problem but only on my smartphone (Android 4.3 and Dolphin Browser). If I use my notebook everything is fine.
What I discovered:
I switch to my utopian team and the background color swithces from red (first team) to grey (second) team. So I know that I'm now with my second team. As soon as I try to go to the forums,the team overwiew, finances or transfer list, the color switches back to red and I'm again with my first team. But this is only when I use the short menu.
If I use the long menu und click there on transfer list or finance, I stay with the second team.
