"[Group]"

Why does "[Group]" appear in the title bar of an Excel file?

 

[Kevin B]

You have two or more worksheet tabs selected and are in group mode. Right
click on a selected worksheet tab and select ungroup to return the workspace
back to its single worksheet default.

Grouping is useful for applying the same formatting, labels and formulas
across multiple worksheets in a workbook file.

To add to Kevins answer, check your sheets that are grouped. What you have
done to one is done to all grouped sheets. As Kevin pointed out it is useful
for several reasons, but to inadvertently have them grouped while entering
data can leave unfortunate results.
