Audio meter and save dialogue issues

Hello everyone,
I'm new to the forum but couldn't find an answer to my questions anywhere so here it is:
I recently updated to Davinci Resolve 17.2.1. build 12 and I encountered two issues that I just can't find a solution to or any settings that might help.
1. When working on a project suddenly the audio level bars in the mixer panel turned red (instead of green, yellow, red) and they stayed like that ever since - no matter which project I'm in. I remember typing in subtitles and realizing my cursor was not in the right window when it first happened, so I guess I must have used some kind of short key. However, I couldn't figue out what kind of setting this might be and I couln't find a shortcut via the search function.
2. Since upgrading DR stopped asking me weather I want to save a project or not whenever I close it. This has already caused me some pain because I messed around in a project and wanted to close it without saving but DR just saved it anyways without asking
Again I was unable to find an appropriate setting for this.
Thank you all in advance for your help!
