Acronis Drive Monitor alarms even when non stop backup is done

I have Acronis True Image 2016 and Acronis Drive Monitor installed. I am backing up the drives C: and D: with a non stop backup with Acronis True Image 2016. The Acronis Drive Monitor still sends an alarm that the drives C: and D: have not been backed up during the last week. Is there a bug fix for this behaviour? I am expecting that as long as the non stop backup is working, no alarms are sent by Acronis Drive Monitor. See also attachment.
