PacklinkPRO - Items imported arent displayed in step 3

[raulbarahona]

Preconditions
One order should be completed in shop with some items (more than one)

Steps to reproduce

1. Navigate to https://es-profront-integration.packitos.com/
2. Login with any valid user (ex. raulbarahona+esproint@packlink.es)
3. Click on imported order
4. Complete Origin and Destination info
5. Click on NEXT button to reach results page
6. Choose any service, and click on Price box
7. Reach Personal data page

Expected results
ALL items imported should be displayed in drop field "Content", above Insurance amount field. Then user should be able to change this value to other (default). We want ALL items present in one option of that combo field.

Actual results
Currently, only first bought item appears in this field. User can choose between others, But no more imported items.
