Bought 2 tix together, need to sell only one. When it asks "how many tickets do you have", technically I have two but I'm assuming it's asking how many I want to sell, right? So I select "one" and then see it wants me to select the correct option, however none of them fit my circumstance (Sell any quantity, sell all, etc). How do I proceed to sell only one of the two tickets please? TY!
