Two subnets with AdGuard Home issue

Hello everyone,

Im not a network expert - I have small home network with Mikrotik RB951ui-2hnd.
I have this situation. In my home network i have two subnets 10.10.0.0/24(private) and 10.10.1.0/24(public). Private subnet can access public subnet, but the opposite is forbidden. AdGuard Home is installed on public subnet 10.10.1.xxx. Everything is working perfect expect " Request history". Every client request from public network (10.10.1.0) is visualize with their own IP address, but every request from private network (10.10.0.1) is visualize with the gateway of the public subnet (10.10.1.1).

What could be the problem?

The problem could be an action=src-nat or action=masquerade rule in chain srcnat of /ip firewall nat, which is not selective enough and src-nats connections from the private network to the public one to the own IP address of the Mikrotik in the public subnet.
