War thunder CDK help - UseCurrentFormation not working

I’m trying to make a convoy with 3 different type of ships but every time i try to make them follow a waypoint they automaticly try to get into a row shape even tough i’m using “UseCurrentFormaton” inside “SetHeadSquad”.

I don’t know if i’m making it correctly but i want to make it so the convoy stay together and not seperate .
Is there an easier way or a reason it does not work ?
