Default Values of Filter panel of form being lost even though UI reflects a value

Hey guys wondering if you can help me

We have a Page with a table and a filter form.

We are setting some default / initial filters for the form which works fine

in the attached image you can see all the filter values are not being attached to the query.

even though in the UI the form shows it has value as per the second image

UPDATE: Ok so using initial values is working in the filter form.
