Problem - duplicate surcharge in several order total modules

[PiLLaO]

Hello,

I have an issue in my osc BS, I try on a fresh install and it works perfectly, so I compare my modified files with non changed files, but I can't find the problem.

with low order fee and with payment type surcharge, the amount is charged x2 so, if the surcharge is 5, it's charge 10.

I don't know where search, I looked everything...

Any ideas will be apreciated :)

Thanks in advance.
