DS-2CD2332-I to PoE+ to DS-7616NI-E2 - what am I missing here?

Hi folks,

I recently inherited responsibility for a system at my business, and am having a really difficult time in getting all cameras onto the NVR. For a bit of background, the system was entirely functional before lockdown, but when we reopened, a whole corner of the building was no longer showing on the monitors. I traced all of the 'out' cameras to a PoE+ switch, and confirmed that switch is running to a port on the NVR. Once done, I learned a lot of tricks here about SADP and some of the harder to find menus on the NVR itself, and here's where things currently stand:

My 6 missing cameras show in SADP, and I've noted the IPs of each and set new passwords.

The 'missing' cameras also show in the NVR camera management menu, below the 16 'set' cameras, only 5 of which are active, and none of which I'm able to delete, in yellow text. When I manually change the information of the existing cameras (IP, password) to the info I've set in SADP, I am given a 'network not available' error in the NVR. The only other irregularity I can find on the networking side is that the gateway listed in SADP for these 'missing' cameras is 192.168.3.1, rather than the 192.168.1.1 gateway in use for the NVRs and my cameras directly running to it, though I'm unsure if this matters as both the SADP app and the NVR itself seem to 'see' these cameras.

I've done hours of digging around threads and haven't yet seen one with this exact issue - any ideas out there?
 
What are the addresses of the 6 missing cams? are they in the 192.168.3.x mode? Maybe something got rebooted or a power outage caused a networking device to return it's default IP settings. Or Gremlins.
maybe try switching the networking side of the gateway device from .3.1 to .1.253 see if anything happens.
 
The IPs themselves are all following the 192.168.1.x range, at least according to SADP. Oddly enough I can't seem to get any IP information from the linksys POE switch itself when I remote into it, as the software for it seems even less intuitive than HIKvision, if that's possible. ;)

EDIT: Scratch that, IP settings in the PoE+ look good, I think
