Hi,
Thanks for providing us some details.
I have tested your scenario/ case a bit and I am unable to reproduce the issue by following your steps:
e.g
1) Enter some values into A1 and A2 cells
2) Enter formula i.e., “=Sum(A1:A2)” into A3 cell
3) Now copy the cell (A3) using CTRL+C
4) Now select some other cell e.g D3 and paste there using CTRL+V
Please double click on the destination cell to see the formula.
If you still find the issue, kindly give us some screenshots or a demo video to show your steps to reproduce the issue on our end, we will check it soon.
Thank you.
