I had the same problem and had to do a few things to resolve it, so if just putting the first cell in doesn't help, try:
- Make sure the cell with the formula is formatted as General (R click, Format, select General from the list, click OK).
- That worked for all of my sheets except one (I am referencing the same cells and replicating across 3 other sheets, all merged cells). To fix it, I deleted the formula, unmerged the cells in both the sheets with the formula (call it sheet 2) and the
referenced sheet (call it sheet 1), formatted them all as general, and put the formula back in to the
first cell (sheet 2), then applied the fix already stated here: just referenced the first cell (of sheet 1) in the formula (e.g. ='Sheet 1'!L7). I was then able to merge
and center both sheets again, and the data was replicated to sheet 2.
For whatever reason, that worked. I didn't have to do this with the 2 other sheets, I just used the fix already stated: I fixed the problem by entering only the first cell in the merged cell.
