A check box in ACF stores a serialized array
'event_status_clause' => array(
'key' => 'status',
'value' => 'Exclude Past',
'compare' => 'NOT LIKE'
),
I also you are using a type of “DATE” for acf date fields. This will not work because ACF does not store date fields in standard SQL notation. You must search these as “NUMERIC”
