Appbuilder Panel displays hidden fields

I made an updateable dashboard to update two fields in UD25. These fields are related to a QuoteHed record which links to the key fields. This is all working fine when I run the dashboard standalone.

When I add it as an AppBuilder Panel, it functions ok, but the fields which don’t display in the standalone Dashboard appear. So I see Company, Key1, Key2 etc which are needed to do the update, but I don’t want them displayed. Why are they displaying at all when the dashboard has Visible unchecked?
