Use the following macro to reset all the options.
Press Alt + F11 on your keyboard. Then from the menu bar on top, select Insert > Module.
Paste the following code block there, then click the run button on top (the tiny right-pointing green triangle).
Sub Reset_Cells()
CommandBars("Cell").Reset
CommandBars("Row").Reset
CommandBars("Column").Reset
End Sub
The second line resets the cut/copy/insert options for cells, the third resets it for rows and the fourth resets it for columns. Hence, this should enable the controls everywhere.
