Status Message

Hi everyone,

I have currently 2 devices in alarm, and when i try to acess the device in opmanager i get the follow info message:

Status Message
Unable to find the object : "ip_address"

I can not acess it, so i can not delete them, and when i try to re-add it it says:
Device already present in system.

Any ideas?

Regards,
Manuel Pereira.
