Host Item created by Discovery Rule cannot use encyrption and templates cannot be assigned retroactivley.

Steps to reproduce:

1. VM guest is discovered through VMware Template through Discovery Rule "Discover VMware VMs" and the associated Host Prototype.
2. Template and Encyption Windows cannot be edited.

Result:
@ Host Prototype: PSK Encryption cannot be enabled

@ Discovered VMs: fields cannot be edited. Any field should be editable here, to further customize the Item.

Expected:
Maybe there is a reason that I don't understand, I am completly new. But why cannot I not fully edit an Item when it was created through a host prototype. If I clone it, it will work, but why do I have to go through this step?

Why can i not enabled encryption in the host prototype?
