Hidden Field Is Still Showing


I made a field hidden on the Lines tab grid of the Purchase Order Entry panel, yet it only shows hidden for me not other users.

I made sure that the panel I made changes to was the All Companies/All Users customized panel. The only other changes I made to the panel was adding a field to the grid. That customization saved and is visible for all users/all companies. However, the hidden field still shows for users (except me) and users are able to input data.

Is there a solution to this or another way to make the field hidden?
