The selecting of this as a one-way is the problem... the poor tool thinks that you are just doing a LHR-LHR flight (for some reason) - changing it to return will get the right answer.
But you're right - putting in a one-way to the same airport should be flagged as an error - I've fixed for the next version, now I think I need to find my own way of scraping these taxes as I haven't had anything back from Salvadors yet about an update
