Connector is getting data only as string but not as values

Hi,

I tried the connector for lookerstudio. However, when I want to pull the data for the visitors each day I’m not able to do that. I think it’s because the data is classified as string and not as values. How do I change that?

Does it have to do anything with the version I’m using?

WARNING: You are trying to connect to a version 4.12 Matomo. This connector works best with version 4.14 or greater. Other versions will not be able to provide Looker Studio with all necessary information.

Thank you in advance!
