Hi

It could be that the OSPF subnets are being learned with a lowest administrative distance lowest via BGP than OSPF or some redistribution or ACL could be the problem. We should verify the configuration to determine the cause, Could you please share the configuration and logs of both devices? and the diagram.

Thanks.
