The flights are 3+ months after the RUC's expire.
The OP had the same result as you, no need for HUCA. OP's itinerary shows seats in D1.
But you are rolling the dice. Your certificates will show as available until your ticket is reissued. It is possible (perhaps likely) that the system will not allow the ticket to be reissued due to the requirement to travel by the date of expiration.
