@Shu are those M.2 drives NVMe or SATA? Some M.2 sockets don't support both. Thats my guess why they only show up in on M.2 socket.

All ports apparently support both, could it be something to do with CPU maybe, I had a asrock extreme 4 and both m.2 worked on that as you could force them in the bios
