duplicating entries

Good morning,
When working in the X-sheet, if we type a letter or number into a cell, it is automatically duplicated in the next cell in the same column. The page is set to overwrite, not insert. Any ideas as to whats wrong?
Thank you.

You may already have the answer but it is due to holds that it is set to 2 from Xsheet Menu>Exposure>Hold Exposure>Hold 2 Cells.

There is a shortcut by default that you can remove it if you do not want to change it by accident.
