Hi Jazzmankg,
By default, the fill handle and drag-and-drop editing is turned on in Excel so that you can drag the mouse to move and copy cells. To make sure it’s enabled, go to File>Option>Advance and **Enable fill handle and cell drag-and-drop,**once enabled, this option is enabled for all the sheets in the workbook.
To test, create a new workbook, type 1 in A1, 2 in A2; select A1:A2; move mouse point to fill handle (note change in cursor shape - see screen shot); drag down to A10.

To utilize fill handle, you must drag the fill handle
to copy data or to fill adjacent cells with a series of data.
You can further try the following suggestions, see if there’s any change:
