This is driving me crazy, how is it that flights are found and priced out on vayama, but I can't find it on ITA?

I am feeding the flights one by one to ITA and once I add a specific flight ITA shows a big fat zero? I don't want to post the specifics on this forum, but this is something that was posted on a different site for C1-C2 and wanted to learn the specifics of this dump.

Please PM me if you know what's going on here. I am starting to give up on ITA, as I thought that it would at least show every flight that a regular booking engine would find.
