Formatted Cell Changes Format When Information Is Entered

[Guest]

I am using a worksheet that someone else set up. When I enter information in
a cell the format changes. I clicked "Undo" and then checked the number and
alignment format and both are set to general and there is an upper border to
the cell. When I enter text the border disappears and the text is centered.
I cannot determined what is causing this to happen. Also the person who set
up the worksheet is no longer with the company.

Thank you.

Is it conditional formatting?
Format>>Conditional formatting
If you select the cell then check the menu you may see the formatting in the
dialog - you can delete from here too.
