My Nexus 5672 is receiving OSPF packets from a remote switch on the wrong area. Somehow packets for area 210 are being sent over area 0. The configuration looks right to me and it is only this one switch that has a problem. We have been experiencing brief outages to the switch for the past few days and I am worried this could be a reason. Error message:
2020 Aug 4 16:24:36 SEC-S5672-A %OSPF-4-AREA_ERR: ospf-110 [4619] (default) Packet from 10.210.215.1 on Vlan2180 received for wrong area 0.0.0.210
This repeats all day multiple times a minute. I can't find anything like this on Google and there is no Smartnet on these switches.
Receiving switch is a Cisco Nexus 5672 and sending switch is a Cisco 3850. VLAN 2180 is the VLAN connecting the two switches through Cogent's network.
3850 OSPF config:

I'm new to OSPF troubleshooting so I'm not sure how to fix this. It's a remote site so I am wary of screwing myself and losing access to them by making a mistake.
