Not sure if this is the right place to post. I'm trying to book award flight using AA miles on QR. There is availability on both Econ and Business class and yet when trying to book, I get this error.

I tried both on Econ and Business, getting the same error. Flight is for November 16, 2023 - DOH-MNL departing 6:35PM. Is there something of a glitch on AA's site?
