This is intended! From the latest hotfix notes:

Quote

Removed broken Public Matchmaking functionality from The Steel Path Abyssal Zone mission. The functionality was not intended and resulted in Steel Path players matchmaking with normal mission squads. Abyssal Zone is intended to function like the old Void Key “keyshare” system, where an Abyssal Beacon requires a premade squad and the Host gets their Beacon consumed.
