Hi, can you explain why I'm seeing the following?

This is a link to a screenshot searching for One World reward availability from TPA->LGW->MAN on 14th May 2012. It shows availability in BA Club World (CS+) on the 2166.

But if I go to the BA website to book it, it shows no reward availability on that flight on the 14th May.

Then I simplified the search on the KVS Tool and just looked for the TPA->LGW sector. This is a screenshot of the result which shows no availability in Club World.

So, should I be able to search using KVS from TPA->LGW->MAN or must I keep to single sectors for this to work properly? Or is there another explanation?

Thanks.
