Problem with ARP - bridge CPE

RouterOS Beginner Basics
1

Hello, can anyone point me in the right direction as to what might be wrong with my configuration?

  1. I have a local network A with the address 10.0.0.0/24
  2. The main router is on 10.0.0.1 - it has DHCP 10.0.0.2-10.0.0.254
  3. The DNS server is on 10.0.0.220
  4. On 10.0.0.250 there is a Mikrotik SXT as a transparent bridge (PTP Bridge CPE) on the bridge ifaceit has proxy-arp set
  5. On the B side there is a router with OpenWRT connected to it, which works only as an AP, without a firewall or other restrictions.
  6. Devices on side B receive addresses from the 10.0.0.0/24 pool and have access to the Internet

Problem:
All devices visible on side B identify themselves with the Mikrotik SXT MAC address…
I have a dozen or so devices with the same MAC address and different IP addresses

What am I doing wrong?

Do you have a pair of Mikrotik devices, or is this connecting to a different vendors AP?
If different see https://help.mikrotik.com/docs/spaces/ROS/pages/122388518/Wireless+Station+Modes as to the problems with multi-vendor L2 transparent bridging.

on the bridge ifaceit has proxy-arp set

Why?

ASUS is the main AP interface and it is the access point to which my Mikrotik SXT connects
