tab disappears when left clicked or right clicked

I am working with a fairly large file size spreadsheet (~2mb) and for some reason, when I click on one particular tab, the tabs disappears as well as the row numbers on the left side as well. However, when I use the shortcut to cycle through tabs (CTRL + PGUP or PGDOWN), all the other tabs work fine, but when I get to this certain tab, the tabs and row numbers disappear. I tried all the google tricks I could find such as maximizing the windows, making sure tabs aren't set to disappear in Excel etc, but this has me stooped b/c it only does it on ONE worksheet within the whole book. All the other tabs work fine until you get to this certain one, then they all disappear, but like I said, once you cycle pass it, the other tabs and even its tab become visible again. (The other tabs don't behave this way when you right click or left click though). Any suggetions on what is causing this and how to fix?

I can right click it (but when I do, the tab disappears, yet the right click menu still comes up somehow) and no there isn't any code for that sheet. I think Excel is glitched b/c there is A LOT of data on this one sheet and it somehow triggered a weird software response and I am obviously clueless on how to fix it. Any other suggestions?
