ip scan,internal ip showing on wan interface

hi, everyone, this is my first post over here,
i’m working with mikrotik routers for a long time and never saw this issue
i have router with static wan IP, set to eth1, when i run ip scan on eth1 i see all my local ip(all of them,active or not) in the result with mac address of my static ip gateway,for ip’s that already assigned to devices,i get to result one with device MAC and another with Gateway mac address,
i’m going crazy, dose anyone had this kind of issue? what is the solution?

Turn off the “proxy arp” setting that you have made on the external interface…

proxy-arp was already off,
issue was from VLAN setting in switch, as was doing the setup remotely ,i didn’t know about whole setup,the guy how did the setup,did a shity job,
all port in switch was set as trunk and one of local port was part of WAN VLAN,
