with the kind help of Ian we have found the reasons for the error messages:
[LIST=1]
Objects which contain an ipv6 address but not an ipv4 address.
Since the SUM does not support ipv6 yet those objects can't be imported
So the id 22005 implements more detailed error messages into the SUM.
Furthermore the agent on the utm will be fixed to not send such objects.
Objects which are bound to internal interfaces. The agent does not
send the data of those objects. So there will also be a fix for the agent.
Id 22005 also implements a more detailed message for such cases
