3825886 - Why am I getting different results when searching for rail availability using the Mixed Flight/Train Search tab versus using the Train Search tab?

I am trying to book a train from SXB to XHP using Mixed Flights/Rail tab, however, no results are returned.



Also Amadeus is not displayed any results. 



When I search the same locations using Rail tab, I get results.
