Hi

I am trying to book a one-way flight on Qatar Stopover Program: November 8th LHR-DOH-SGN, staying in Doha for 2 days. I want to take the 21:30 flight LHR-DOH on Nov 8th, and the 8:05PM flight DOH-SGN on Nov 10th. But I couldn't find the 21:30 LHR-DOH flight in the Stopover Program booking page, only those departing at 14:55, 14:15, 8:5, 8:35 etc are available.

However, if i try to change my stopover to only 1 day, that is, flying out of DOH on Nov 9th instead of Nov 10th, I could actually select the 21:30 LHR-DOH flight. This makes me believe there's a bug on the system. Does anyone experience anything similar and how to solve this? thank you very much
