Preview jumps to previous highlight whenever I highlight; also you can't undo when it highlights the entire document

As the title says, whenever I highlight in Preview, it jumps back up to the previous highlight. My friends have experienced this too, and we all express a lot of frustration since we have to annotate very long pdfs and it takes forever to scroll/click back down each time lol... This is a recurring issue and has been since I got my Mac.

The other Preview issue I have is sometimes after I highlight (I select first and then hit highlight. It shouldn't stay on, but that's for another time) I press Cmd + S to save, but I fat finger it and hit Cmd + A. That then highlights the entire document and I can't Cmd + Shift + Z or undo it in any way. If you hit Edit in the menu bar, you won't even see that the action was performed. The only way I've found to reverse it is to individually remove highlights from each page, but that also removes any previous highlights I had. See below:

When I "remove highlight" it removes highlight from the entire page (and not the entire document).

Below is another document before and after. You can't see that the action occurred under "Edit"

I assume this issue is because of the coding that separates each page into a separate item — You can't drag text boxes across pages or undo multiple-page actions. But you CAN highlight all pages. Someone help please? Also, can an administrator make a Preview topic to improve Preview
