Hi everybody,
I planned my trip and added them to my Global Pass so I already have tickets, but some of my train needs reservation. When I tried to book the first one from Milan to Frankfurt with the Rail Tool I saw available seats but it was impossible to add one to the chart, and it says that "the train has already been added tfor all travelers. Remove it first before making a new selection" (see picture). If I try to book another random train everything works.
Did I do something wrong, maybe? Thank you!!
