"No difference report was found" Error

I am trying to test SAP NW-GATEWAY OData with DV6-ER4 and JDBS 7.0.1.GA/Designer 8.3.0-CR1

The following steps will reproduce the error:
1. Do an import/Designer/Teiid Connection >> Source Model
2. Create a new datasource using webservice from available drivers
3. Enter Data Source Properties (can connect to the url in a browser):
URL: https://sapes1.sapdevcenter.com/sap/opu/odata/IWFND/RMTSAMPLEFLIGHT/
WebService Security Used: HTTPBasic
class-name: used prefilled default
Authentication User Name: P1940027560
Authentication User Password: Foxrun1004
4. Selected the newly created driver and selected "Next"
5. Selected sap-nw-gateway translator and named the target model and selected "Next"
6. Was presented with a DDL screen and selected "Next"
7. The "Select the Differences to Apply" screen shows an Import Message "Error
encountered while importing the DDL - No difference report was found". screenshot attached.
