Hi Scott,
As I know, this design in SteadyState is the same as SCT. As I haven’t experienced this kind of issue before, I would like to confirm your update method and frequency. Based on the design of this product, I recommend updating through Schedule Software Update, and update weekly.
By the way, if your organization requires regularly changes, instead of following a fixed schedule you set within Windows Disk Protection, you might want to consider whether Windows Disk Protection is right for your environment. Based on my experience, some other management tools such as group policy and Microsoft Systems Management Server (SMS) can manage clients better than SteadyState.
I also found a related article about this kind of issue for your reference:
