Affection from before 4.0 not converted to Influence post 4.0

[Jarrogen]

As the tital says, I had maxed out the affection of all my companions on my main in SWTOR before 4.0 hit and now each one that I have access to has and influence level of 1

It was stated time and time again that affection would carry over to influence, that a maxed affection companion would become a maxed influence companion

Sounds like a bug. I would put in a customer support ticket.

I've not seen anyone else report this problem, are you sure you aren't just reading the screen wrong? They should all be rank 10. Try using a couple of companion gifts (can be bought on fleet) and see what happens.
