v3 contacts endpoint - Query parameters are not being recognized.

The endpoint I am requesting is: https://api.cc.email/v3/contacts?lists=70f344f0-7327-11e8-a6f5-d4ae529a8250&include=custom_fields&limit=10&include_count=true *this is a test list that only includes 3 contacts.

 

Each parameter added, does nothing to my response, its always returns all contacts

 

What I have tried:

- various contact list id's

- [email protected]

- ?limit=10 - returns 50 per page

- ?include_count=true - no count returned

 

When I test the contacts endpoint from the API Reference page, I see the correct results, but they're not being reflected in my GET requests.
