We have the same issue, additionally it will say automatic updates disabled on the client machine. If I manually set it to automatically update on the client machine, the next reboot it will be set back to disabled. I have revisited the agent settings for MAC and it is set to update core first fallback to internet.
I reached out to Ivanti on this issue a while back and it is a known issue. I was lead to believe it would be resolved in 2017.1 but it is not. We can hope for the next release..
