Adobe Campaign Standard API linked custom resource: GET request returns too much

Hi,

I have noticed that when performing a GET request  on a custom resource it returns a LEFT JOIN with the profile so it returns all the results from both the Custom Resource and the Profile it is linked to. 

GET https://mc.adobe.io/<ORGANIZATION>/campaign/profileAndServicesExt/<resourceName>/

How do I then make sure I only get the result from the Custom Resource?

I've tried with filters but that doesn't seem to work either, it still returns as many rows as the number of relations to the profile table it has.

This appears to be a recent change to the API it seems because previously I could make a GET request that would only return the rows in the custom resource table.

Cheers
