Have you had that problem before? I know someone did...

When you open Excel, go to Tools?Options.

Then go to the "view" tab. The bottom section of that tab is
called "window options". Basically everything in that lower section
should be "ticked" except for the "page breaks" and the "formulas".

Your problem sounds like the "sheet tabs" box is unchecked.
