Strange issue with UI in config/edit mode

I haven’t really touched my HA UI setup for a while, only editing automations/scripts.
Today I wanted to change a few things and noticed that my edit ui is messed up/missing elements, eg. the sorting numbers of the elements in horizontal/vertical stacks.
I’ve tried to clean up my themes and throw out all the stuff that might cause it. It is the same on all browsers and also the iOS client… any idea what causes that?

no one experiencing this? I’m still having this issue - which makes editing the config quite a pain as
I have to use yaml for most of my stuff :frowning:

silly me - had to clear the browser cache. But as it happened on all devices I had dismissed this option at first…
