Looker does not show real data

I have activated Apigee API Analytics in the Apigee platform.
Then, in Looker Studio, I have configured as data source the Apigee connector and entered the correct project ID.
Despite this, Looker does not show real data about Apigee.
For example:
- There are 4 developers, but Looker only shows 2.
- There are 17 API proxies, but Looker only shows 4.
- There are 6 API Products, but Looker only shows 2.
And so on with the other dimensions.
What is going on here?
