Arp Request - Different Sender Macs

I’m experiencing some really strange connectivity issues over a wireless bridge (trapeze). Attached is a pcap of the arp request and reply(trying to ping router 10.19.16.245 from 10.19.16.222).

The ethernet senders mac address is actuall f0-xx-xx-xx-xx-xx not e0-xx… Notice the arp section, sender mac is correct. If I change the mac address on the windows end station it resolves this issue. Does this make any sense?

Capture is from port 12 on switchX

end station connects to switch (wired), switch connects to access point (mesh), connects to access point (portal), connects to switchX port 14, mirroring to port 12, router is beyond this switch via fiber and other switches).
