Duplicate IP addresses in gravity Zone

Hi all,

I have an endpoint on my network that is showing a duplicate with the same IP. The endpoint is a Mac running the latest BigSur update. When I try to remove the duplicate, it either affects the user to where they cannot perform their task or the duplicate and non-duplicate switch places (if that makes sense). The user had noticed some strange activity and reinstalled their OS. I'm honestly at a loss on this one. Has anyone seen the same kind of thing?
