Entitylist filter not working for lookup field in Power Pages

I’m trying to filter an Entity List in Power Pages / Dynamics 365 using Liquid so that only records assigned to the current user’s parent customer and if lookup is null are displayed

{% assign parentCustomerId = user.parentcustomerid.id %}

{% if parentCustomerId %}
    {% entitylist name: "Available Units" 
       isModern: "true" 
       filter: "udc_unitassignment eq '" | append: parentCustomerId | append: "'" %}
{% else %}
    {% entitylist name: "Available Units" isModern: "true" %}
{% endif %}

What I expect:

If parentCustomerId exists, show only units where udc_unitassignment equals this ID.
If parentCustomerId is null, show all units.

What happens instead:

The page always shows all records, ignoring the filter.
Debug messages in Liquid ({{ parentCustomerId }}) show the correct value.

Questions:

Am I using the correct syntax for filtering an Entity List by a lookup field in Liquid?
Is there a known issue that prevents entitylist filter from applying to lookup fields?
Are there any special requirements for server-side filtering on udc_unitassignment .
