I think, I have a solution:
In the profile settings and then in the layout settings, the checkmark next to "Overwrite settings of whitelist and blacklist with this layout" must not be marked.
You will have to restart the device.
Then you can see the standard Apple apps, but you can block them via the blacklist.
