Here I show how to set up a Mikrotik HAP ac lite so that it has 2 lan's each with WIFI and internet, but that cannot communicate with each other. 

Here are my notes; 
Interface remove interface from master/slave, 
Add new bridge, 
Add port to bridge, 
Add IP address to bridge, with network address, 
ip - firewall - nat add a nat rule - srcnat, src address from network, action masquerade, 
Ip - dhcp server - setup dhcp and follow guide for new network. 
Networks both working…. 
Wifi, add Security profile, set to dynamic keys, set WPA1/2 and set keys. 
Wifi, add virtual interface, set name, set SSID, sec profile and master ports, 
Add bridge ports, add the new wlan(s) to the new bridge
Ip firewall add 2 filter rules, 
Forward chain, in bridge 1 to out bridge 2 action drop 
Forward chain, in bridge 2 to out bridge 2 action drop 

There are more than one way to achieve this, this is just one way.
