Set carriers options problem...

[promod]

Hello

 

I'm working with Prestashop 1.5.4.1 and I'm trying to set carriers's options.

 

I  have 2 carriers

 

- free carrier if the customer come to the shop to take his purchase

- basic carriers to send products

 

But I can't display both carriers in the cart at the same time. (all my carriers are actived..)

 

Can someone help me please ?

 

I noticed that each time I edited a carrier, Presashop has made a new entry in the table ps_carrier... it's normal ?

 

Thanks
