ipscan results wrong

running ip scan under tools in winbox shows 10.20.7.199 on my hotspot interface, but that mac address is my laptop running DHCP and the router has assigned it 10.20.7.198 according to the hotspot active users page and ipconfig on the laptop.
I can’t find the right syntax in the 2.9 manual to run ip-scan in a terminal window.
IP pool used addresses in winbox shows both .198 and .199 assigned to the mac of the laptop, 198 says its owner is hotspot (the interface name), 199 says DHCP.
