How do i get back Collumns ?

How do i get back Collumns ?

Hi,

in the contract section someone unchecked all collumns, even the Edit/Change button.
Because of that the button to edit the collumns is gone.

Is there another way to get the collumns / button back ?

I have send a Screenshot to be more clear in what i mean.


Hope you can help me.
