Why no items with completed status are returned by query?

Hi, mates.
I can fetch items with only non completed status with my query. This is strange as I have no rules applied for the items_page object in my query. What might cause this behaviour?
query {
boards(ids: 2360058426) {
items_count
items_page {
items {
group {
title
id
}
name
state
subitems {
name
column_values {
column {title id}
value
type
}
}
}
}
}
}
