Hello there, I am trying to book multi-city flights, from IND to London, then Brugge to IND. When I select the first segment (IND to London), I can't find a way to select the flight for the next segment (Brugge to IND). I only have options to select a different initial segment. There is a dropdown on the left for the second segment, but clicking that doesn't do anything.

I tried a search for a roundtrip to compare, and there was a clear tab for outbound and return trips. 

I am on a Mac and tried Chrome then Safari with the same results.
