Hi Monika,
While you are in the table maintenance view, click on "System" in the menu bar, choose option "status" from that. A dialog box appears in that you can see the screen number. Double click on the screen number. It'll navigate you to the Screen painter. Click on layout, choose change mode, and choose the column name you want to change and change the description and activate the screen.
Hope this will resolve your issue. Reward if this is helpful! Image may be NSFW.
Clik here to view.
Thanks,
