Field Filter not working when selecting a value

Hey there!

I am working with a query with multiple CTEs and wanted to add a Field Filter. However, every time I select a value in the dropdown menu I get this error (if I do not select any value, no errors):

ERROR: invalid reference to FROM-clause entry for table "mdl_customers" Hint: There is an entry for table "mdl_customers", but it cannot be referenced from this part of the query.

I already removed all aliases from the query to make sure there are no issues with them. Any thoughts?

Here is the query:

WITH 

emp_in_ind AS (
    SELECT
        customers.country AS customer_country_name,
        customers.customer_name,
        contract.job_title,
    	CASE WHEN contract.contract_end_date <= contract.contract_start_date THEN 1 ELSE 0 END AS terminated_before_start,
    	CASE WHEN contract.contract_end_date <= current_date THEN 1 ELSE 0 END AS terminated_by_now,
    	CASE WHEN contract.expiration_date <= current_date THEN 1 ELSE 0 END AS contract_expired_by_now,
    	CASE WHEN contract.contract_start_date <= current_date THEN 1 ELSE 0 END AS already_started,
        contract.salary_source_amount AS base_salary_usd
    FROM contract
    JOIN customers
        ON customers.pk_company_id = contract.company_id
