Mobile Control with iOS Supervised Mode all apps gone besides settings

Hi,

I installed Sophos Mobile Control on an iOS 12.2 device with Supervised Mode on. After the installation of Mobile Control all (native) apps disappeared including Mobile Control itself. The only "app" which stayed on the phone is settings. Is this a missconfiguration on my side, the expected behavour or a bug? And how do I get the default apps like Messages, Calendar or Mail back?

Thanks in advance
Cheers
