Spreadsheet Data Incorrect

Spreadsheet Data Incorrect

Hello,
I have recently had some issues with the spreadsheets. After cutting a row, the data in all but one column was shift up in about 6 of the 70 rows. The row below the cut also was copied and pasted over the second row below the cut, deleting all of the data in that row. This is incredibly frustrating, and double my work time while trying to see what was incorrect and what was correct. Please tell me how to avoid this in the future. Also know that I have exhausted all user error possibilities.
