Orders are always placed with the first carrier

[Ingyser]

Hello,

For a month it has been happening in my store that all orders are made with the first carrier. It does not matter which carrier you select from the 5 different ones that are configured. The order will always be completed with the first carrier on the list. But if I disable the first one, it will be done with the one that has been left as new first.

Interestingly, this only happens when choosing a payment method that involves a real payment. That is, payment by credit card... It does not happen with cash on delivery, bank transfer... With the latter it is done correctly.

I have tried disabling the carrier modules and the problem persists. I have also tried to save all the carriers so that the IDs are regenerated but there has been no result.

I have seen that in ps_cart.id_carrier the carrier ID is updated every time I change the carrier selection at checkout.

Any idea where the problem may be?

Thank you.
