Office 365 -- Excel -- Text or Data Typed into Cells Not Appearing on Macs

Sometimes, if you are using the Excel spreadsheet program on a Mac, and you type text or data into a cell, the data won't appear in the cell.
It usually will appear in the function bar or box, though.
Regardless, for whatever reason, if you click out of the cell, scroll the Excel spreadsheet down so the cell with the new text or data is completely out of view, and then scroll back up again, the text or data will appear in a cell.
