I appreciate the extra screenshots and information on what you’re experiencing 
Webflow uses both a Designer and an Editor, however it looks like you’re referring to issues with the former based on your screenshots. Can you confirm the problems persist in an Incognito window with all extensions disabled? It’s not uncommon for browser extensions to cause wacky behavior with Webflow given it’s a browser-based tool.
If it persists without any extensions enabled, I’d recommend you reach out to support to see if they have any extra information to provide. I’ve been using the Designer myself this afternoon and haven’t noticed any of the same issues you’re mentioning, so it sounds like an isolated issue. The status page appears to show no issues on their end, so I’m inclined to think that it’s not widespread.
I’m sorry I can’t be of more help, but I’m just a customer like yourself so my ability to diagnose specific quirks with the platform are limited. Hope things resolve themselves
