Thanks @paul1974, that was very quick - replied to it before I had a chance to post back here.
I've removed it now, if you can restart your router and do a lookup again, it should show dynamic.
Yeah oddly there was no ticket @Marsh (I've sent you a message on Teams for when you're back in)
Thanks @Gandalf . I'm seeing a new IP and the PTR record no longer shows my username.
