Current version "4.4.4" still listed as "out-of-date"

I manage about 600 machines through Avast Business, remote tool and Anti Virus, and recently pushed out the latest update (4.4.4). However, when I go to the master device list of all my machines and filter to “out-of-date” versions only, almost every single 4.4.4 machine remains. When I filter the list to “current version” only a small handful of machines appear, all of which have 4.4.4… What’s going on here? Any helpful information would be greatly appreciated. Thanks a lot.
