Transportation problem and purchase total

[Edgar Guzman]

Hello guys I have a problem explain:

I have a store with 2 types of carriers, which are assigned to specific products.

When placing an order with only 1 type of carrier, everything is processed correctly.

When generating an order that has 2 carriers is where the problem with the TOTAL amount is generated, we know that the total amount that is the sum of (Total products + Total shipping + Total tax ), in the summary of the order gives me good. But when I click on the CONFIRM MY ORDER button and it sends me to the Order Confirmation screen, the total amount is not correct (it shows me the amount only of the products that are assigned to a specific carrier, the other products assigned to the other carrier and the cost of that other carrier is not taken into account)

Can you help me please


NOTE: I do not use any shipping module
