Warehouse fee delivery

[Blawdi]

Good evening,
 
I just did a test with the warehouse , the site worked before without warehouse .
 
Version 1.6.0.14
 
So all items are in default , except one that I put in a warehouse before I create or choose the two delivery methods ( In the creation of the warehouse and not the product):
 

 
On the delivery when ordering it's been this:
 

 
 
AND despite the choice he always takes letter followed VEL ( € 3 ) at the time of payment ...
 
I do not understand why he offers Colissimo whereas provisions should be proposed :
Letter followed letter followed VEL +
 
Please , called me I screwed up ...
 
In theory it should propose :
Letter followed (2.99 ) + Letter followed VEL ( € 1 ) or total shipping cost : 3.99 right?
 
Thank you in advance
