Panels sometimes do not expand when clicking on an icon in the right-hand column of panels. It seems random. Sometimes the panel you choose expands when you click on the icon (as it should), but sometimes you have to click the two little chevrons pointing leftward at the top of the column of icons, which makes them all expand and it's a mess to work with. Only the one you click on should expand, but sometimes it doesn't.

This isn't a new bug. There were previous submissions about this and the issue was supposedly resolved, but it is NOT. The comments are closed, so I couldn't comment on there that the issue is not resolved. This has been happening ever since the first upgrade at the beginning of the year. I'm on the latest update and still having this issue.
