Without a video showcasing the issues or a read-only link so folks here in the community can take a closer look, it’s going to be tough to say what the issue is. I wouldn’t worry too much about anyone feeling “shame” at Webflow — most of the folks responding here are users like yourself and the goal is to get the site working as you’d expected.
As @memetican said, it could be an issue with the Designer due to your browser environment (ex: conflicting extension/add-on) so I’d recommend you rule that out by opening the project in an incognito window (with all extensions/add-ons disabled) and let us know if that fixes your issues. If that doesn’t work, feel free to include that video and/or a read-only link with instructions on how to reproduce the problem and I’d be happy to take a peek.
