You have two windows of the same workbook open. Close one of the windows by
clicking the x button (the inner button at the top right corner of the
window; not the outer application button). Be sure to save the workbook
after.

when I open a workbook in excel it opens 2 duplicate workbooks with the
extensions .xls:1 and .xls:2
How was this created and how can I get rid of it?
