I want to report a problem with the Layout Grid

ISSUE 1: I cannot see the Layout Grid even if it’s already enabled on my screen. On the other side, it’s visible on my Figma Web. I can’t figure out how to solve this issue.

ISSUE 2: If you see the last image, I am getting those BLUE lines without any reason.

If anyone knows how to resolve these issues, please comment with the solution. Thanks 🙂

Software details:

OS: MacOS Big Sur 11.5.1

Figma v99.0
