OSPF RID duplicate from itself

I recently had an issue where OSPF RID duplicate messages popped up on N9K switches.

Both N9K switch is interconnected with L2 link and running HSRP.
They have 192.168.1.252(SW#1) and 253(SW#2) as their SVI IP.

 %OSPF-4-DUPRID:  ospf-10 [1287] (default) Router 192.168.1.252 on interface Vlan100 is using our routerid, packet dropped 

This log was captured from SW#1. SW#2 also had the same log entry with the address of 192.168.1.253.

So it basically tells me that there was an OSPF RID conflict from itself.

What can cause this issue? Bridging Loop perhaps?
