Can't edit Profile 2 Types anymore

Hey guys,

i've got quite a heavy problem.
After a Drupal Core Upgrade, Profile 2 is not working anymore, as the way it is intended.

Here's my problem:

Normally you can edit under People/edit (a specific) user and get tabs in the upper right corner, where you can edit the profile type fields of a user.
But at the whenever i try to click on one of the generated profile tabs, it changes the url to user/*id/edit/*profile type but nothing is happening. It stays on the same info page, where you can edit your password and so on.

Is there a dependency i'm missing except the entity module ?

Thanks for your help guys,

appreciate it !
