I suspect you have only recently started using both wired and wireless. If so then this is why your seeing the change in upnp
i take it 192.168.88.219 is wifi and 192.168.88.149 is wired. if this is right then your wified connection from ps4 was first to connect to game and has kept the port open,, resulting in other connection to use another external port.
As for 9307-9308. at times this happens especially if the lowest port was previously used by another device
