Yesterday, my keyboard was malfunctioning, which caused a shelf I clicked on in the game desktop to disappear. I couldn't find it anywhere on the desktop. When I opened the shelf menu to create a new one, it showed that the shelf was already placed. I couldn't close these shelves that were previously placed but had somehow vanished and couldn't be placed again. I tried reinstalling the game and redownloading/installing the mods, but the issue still persists.
