I have two new IPC-T54IR-ZE-S3 cameras with the latest firmware. When I try to create an IVS rule, I'm not able to save it. I draw the region where I want to have detection, but when I select "Next," I get the error that says, "Please draw graphics." I think something similar is happening when I use the Video Metadata to try and draw an exclusion area for vehicle detection. I draw the area, I click apply, it says everything is good. But when I go back in to that screen, the exclusion area is no longer there. Am I doing something wrong?
