OME Report Includes Devices Not In Selected Group

I created multiple reports to show Critical and Warning status devices in different groups. There is no overlap in which devices are in which group, so there is complete separation between the groups. For some reason, when I create a report that is supposed to only look at one of these groups it includes a random number of devices that are not in its group.

I have 3 reports that look at 3 distinct groups which cover all of the devices that OME is monitoring, so all 3 reports should together show me all devices in Critical or Warning status. None of the reports give only devices in their specific group, but all of the reports are different from each other. Which means there is nothing consistent about this error and they're just pulling other random devices from other groups into their report.

Any ideas?
