Presets in Lightroom suddenly vanished

Hey,

I have been using the updated Lightroom desktop version 4.2 for a few days now, tried out the Presets, which are brilliant. But today I noticed, that the Preset button, which was where the "edit" button is 2 days ago, is nowhere to be found, and I have been wondering where it could have gone. I also updated my Mac , but only a security software thing of the current version, the Catalina system 10.15.17, no completely new software, and am wondering if that could be it. Has anyone experienced this? I have googled everywhere but could only find 8 year old posts, and nothing relevant.

Cheers!

PS: I attached a screenshot. its in German, so the layout might be different, but next to the "Automatisch/automatic" & "Black/White button" is the "edit" button.
