Keep Coding

5 days ago I used an adwords script to label every single ad in an account, and with success: Every ad has 4 labels, no more, no less.
Now, 5 days later, when I want to fetch the ads with the labels, the data it returns is incomplete. Some ads have 4 labels, some 3, some 2,... you get the point.
The AWQL query I use is this:
SELECT Date, Impressions, Clicks, Conversions, Cost, GmailForwards, GmailSaves, GmailSecondaryClicks, CampaignName, AdGroupName, Labels, Id, AdType, AccountDescriptiveName
FROM AD_PERFORMANCE_REPORT
DURING XXXX,YYYY
I'm using the dev_appserver that comes with the App Engine SDK 1.9.40. The CSV I get in return does not contain the labels either, so it's not that there is a bug somewhere in my code that doesn't read everything from the CSV.
I am using googleads 4.6.1
