Shipping Method isn't good one displayed on preview page if method has Category requirements restriction

[pedrito92-a]

Hi,

On the preview page, I have a problem with the shipping method displayed.
During the checkout process, after selecting a carrier with categories requirements, when I preview the order, my previously selected carrier changed with the default carrier after the orderProcess methods executed.

During the creation process, the available shipments are good. I select Fedex (config in the image)

On the preview page, and during the save order process, the shipping method is reset with the default shipping method

Fedex configuration:

The CategoryRequirementEligibilityChecker is blocking because the order has no shipables.
How can I make this checker eligible?
