when I open the firewall, I found that there are two red lined (I think mean invalid) which are created using the fallowing lines:
/ip firewall filter
add action=jump chain=forward comment="Check if dest is an open customer" disabled=no dst-address-list=open-customers jump-target=open-customers
add action=jump chain=forward comment="Check Known Bad Hosts" disabled=no jump-target=bad-hosts
Note: I have RouterOS v4.14
