Make sure you submit final right after you submit your solution. I've noticed not doing it that way sometimes doesn't show my solution where you say.

There is a known bug (reported here) which makes your solutions sometimes not appear on solutions page. But it usually does not prevent you from getting Honor. I will take a look and check if there's something wrong with your solutions, but I can already see that 7 of them failed grouping and do not appear on solutions page.
