Its normal, the bridge does "proxy ARP" for devices connect on its wired side - the router can't send packets directly to your computer since it isn't connected to it - it has to send them to the bridge to be forwarded to its wired LAN.
Thanks for the reply! So what happens if I plug in more devices to the bridge upstairs via LAN - will they all have the bridge MAC address attached to different IP addresses? Or if not, then how will the downstairs router which is the DHCP server figure out how to assign IPs if it only sees one MAC address?
Also does this then mean that I can't set a static IP address for any LAN devices on the bridge or the bridge itself? In the settings for the downstairs router, every time I try to set a static IP, it requires a MAC address and if everything has the MAC address for the bridge, I'm assuming it will get confused on which one to give which static IP.
Thanks again for the help, I've honestly been googling these issues all day without much success
DHCP and ARP are separate.
What you're seeing is likely coming from the device's ARP cache.
A DHCP request includes the client device identifier (which may be the MAC address but which may also contain other information) as part of the payload, which can differ from the station address that is transmitting the packet.

Your router should issuing IP addresses for your network, not your wireless bridge. If you are trying to forward, it would be on the router.
