Having trouble using buttons to change EN16 pages

I’m setting up the EN16 in the grid editor to use with my DAW. I copied a template that used the top four buttons to switch banks. I’m using the rest of the buttons on bank A for transport controls and encoders for automation control. However, I seem to have lost the setting for the first button to go to bank A. I don’t know enough about editing with the grid editor to recreate this button from scratch or by copying then modifying the other three buttons on the top row. Still finding the grid editor a bit daunting. Can anyone help or steer me in the right direction? Thanks!

Actually, just checked and I don’t see any of the bank change functions attached to the first four buttons. I must have lost those as well.

I’m also getting this when I load the custom configuration
