Habmin does not show correctly


I am running openHAB 2.4.0~20181029224406-1 (Build #1405), installed via Openhabian. I just recently noticed, that Habmin does not display it’s content correctly anymore (see screenshot). I tried to reinstall it, but nothing changed, still missing elements in the GUI. Any ideas how to fix this?

Thanks a lot!

Solved. Problem seems to be the Edge Browser.
