Profile image dialogue missing

Hi

I am running UM together with bbpress and the bbpress integration.
I have a problem with the upload/change profile image dialogue atm. Wasnt there right from the beginning.

When I click on the cog icon the dialogue opens perfectly. When I click on the camera icon on top of the profile picture I get redirect to the same page in non-edit mode. The change/upload profile image dialogue is visible while this redirection happens but cannot be reached or displayed before and is not available to click.

I dont know how to address this, cause for a general conflict I would expect all dialogues to be missing. No error message on the browser console.

thanks
KR, Jay
