SSR2013 MS why is "Attention Needed"

Hi,

we see the status report "Attention Needed" for several PCs in our management console. There is an explanation for possible reasons for this report if I click on "Attention Needed". However, none of these possibilities seem to apply (i.e. the backup policy is assigned and has run recently on the same day, the computer missed none of the scheduled backups and there are recovery points for every partition on the same day). So why do I see this irritating report then?

Any ideas?
