SQ02 layout sets

This may be the wrong forum for asking this question. If so please point me to the correct one.

Someone in our system has limited the fields available for changing a layout set on the opening screen of SQ02. I've tried in vain to locate a default layout, but no success.

I used to have 14 fields available for changing the layout set in SQ02. Now there are only 5.

Does anyone know how I could restore all the fields available?
