Problem with filtering on adwords labels in Data Studio
I'm quite new to Data Studio, and I'm trying to create a simple report with just 2 elements: historical quality score (taken from Supermetrics, as the one from Adwords is just a dimension) and the date.
As I have attached a label to the campaigns in Adwords that I'm testing, I'm trying to filter it, but it doesn't work.
What I found out is that if I filter with campaigns with just one label, it works, if the campaign has 2 or ore labels, it doesn't.
Is this a Supermetrics problem?
How should I build the regex query so that it can get the correct data?
