Question about Mercenary contractor (at imperial age)

Playing latest version of AOE3 DE on steam.

When I advance to imperial age by picking mercenary contractor, which says

they give outlaws 50% health and attack bonus, but nothing happens to them actually.

It only gives bonus to mercenaries, not outlaws.

I checked this multiple times with various European Civs.

I think outlaws are useless anyway on imperial age but it’s confusing.

The outlaw thing is an old text that hasnt been fixed

The actual outlaw upgrade is integrated into the tech in the tavern

It gives all outaws shadow tech per age

+20 in age 3, +30 in age 4, +50 in age 5
