Application Installer does not load it's entries

Hi there,

after installing RHEL 7.2 i tried using the application installer in order to install software such as an integrated development environment. Clicking on the development category, there are six entries in my case but they are blank and do only contain some sort of loading indicator (see screenshot). Even after hours the result is still the same, and reloading didn't solve the problem either.

I get no error whatsoever... does anybody had the same issue or is this my mistake?

Greetings

P.S.: Thanks for the developer subscription! ;-)
