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. The cell is not
conditionally formatted. Also the person who set up the worksheet is no
longer with the company.

Thank you.
