datasource.error: we don't support duplicate properties in the feed

Hi

I'm using powerBI with Dynamics 365 (CRM, Sales) online. I added a relationship in the contact entity that points also to contact (basically a circular relationship.) I needed a new one in addition to the out of the box contact to contact relationship, to support a different business requirement.

After I did that, I can't use the contact feed in PowerBI. Here is the error I get:

DataSource.Error : we don't support duplicate properties in the field

Details :     DataSourceKind=OData     

DataSourcePath=https://*****.api.crm3.dynamics.com/api/data/v8.2     Property=mem_ParentContact

Any ideas?
