Hello,
When I use the AdWords API to fetch biddable ad group criterion, say by ad group ID, the returned results always include 2 duplicates of each criterion. This does not happen when fetching any other entity.
The returns fields are exactly identical. So for instance, if I have 10 criterion in an ad group, the API will return 30, so for each keyword there are exactly two duplicates.
Does anybody know why this could be? Again, it does not happen with any other entity as far as I know.
Thank you!
