Read-only grid in interface is not updating

I made some changes in my interface through the Edit List function but when I save changes and update the interface, this changes do not apply to the read-only grid. I tried to eliminate this read-only grid and add it again and this way the changes were applied. 

Example of the changes and the interface are the following:

The changes to apply in the interface are the following:

And the interface remains unchanged (notice the "€" sign is not applied):

Does anyone know any other (less sophisticated and destructive) way to update the read-only grid and directly apply new changes?

Thanks!
