Google Ads - Data Studio Data discrepancy

Hello,

I am trying to create a report to show me number of ad groups, ads, and keywords. However, I am getting wrong numbers (a lot less than what it is actually). I am trying count and count distinct for ad, adgroup, and keyword IDs and names but all give wrong numbers. 

I get other data without a problem (cost, clicks etc) but the counting does not work. 

Thanks in advance for your help,

Enes
