Error message when creating discount

Vote:
 

When creating a discount in episerver back office I recieve the following error: Content with id '11663 is of type 'Castle.Proxies.SalesCampaignProxy' which does not inherit required type 'EPiServer.Commerce.Catalog.ContentTypes.CatalogContentBase

The discount is anyway created and works as expected. When I decompile SalesCampaign I can se that it inherits from BasicContent. 

Has someone encountered this error before?

Thanks in advance.

Did you use the Marketing UI to create the promotion? or did you use code? Which promotion type did you create?
