Yours is slightly different though as if both sectors are visible via smart search I would have expected them to be bookable even if using airline search. I am not aware of TG having married segment logic for awards but maybe that has changed.
They were not only visible, but bookable separately, I was able to go all the way to payment. They showed up under smart/star search but would error out when trying to book. It was TG PER-BKK-PVG with overnight in BKK (long layover). I suspect the layover is the issue.
