Check three things: (1) the proposal's status must be Signed and Approved, Partially Paid or Past Due — New, Sent, Rejected, Fully Paid, Completed and Archived proposals are excluded; (2) the event date (not the due date or creation date) must be between your Begin and End dates; (3) the proposal must belong to the active kitchen. Also note the default range is only the last week, so widen the dates for future events.
