求助！！已订了全程的DB（app），但被告知预订错误！因为必须有所有同行人员的detail ！但是预订的时候可选项目（同行人仅提供岁数），我作为持票人预订！
1.是不是必须每个人注册一个填写信息的意思？
2.我所有的票作废了？是否有变更的可能性？我订的是指定票。
邮件如下
Please note: You are not able to purchase tickets for somebody else in the DB Navigator app. During the
Booking process, you only declare one of the travellers as the ticket-holder, with their personal details. Accompanying travellers are not separately identified during the
Booking or travel and their names are not mentioned on the ticket.
