Hi, I have come across following results, which dont make sense (screenshots attached):

1) I've ran a search on a business flight from London to Singapore (parameters in first screenshot)

2) Search yielded in price matrix, I clicked on first fare on 8th May (£3,030), which I would expect to be the best deal for that day ("cheapest")

3) In the next view (after clicking £3,030 in previous matrix), I can see the cheapest to be £2,131)

Can somebody please explain why prices are different in steps 2) and 3)?
Anything to do with my settings/selection in step 1)?

Thanks,
Peter
