Visibility Issues in Advanced Editor

I'm not exactly sure how to word the problems I have been having, but I'll do the best I can! Every time I go into the Advanced Editor and select an item, everything (other than the element I selected) disappears. When I go back to the Root, nothing shows back up, so it's basically blank despite having a preset with many elements. This has been happening to me since the update to 3.28, but I didn't report it because I figured it was just a bug that would get fixed. Unfortunately, that hasn't happened, so it has been extremely difficult to change anything in KLWP. I'd appreciate any advice/help to correct this issue :) Thanks!

You pressed the "hide other elements" icon on the editor, please uncheck it (its the one with the layers and a slash on top inside the editor preview on the right bar)
