请看下面的说明:
当must后接完成式(即must + have + 过去分词),作“一定已经”讲,表示对过去的推测时:
a.若有表示过去的时间状语,则疑问部分用didn’t / wasn’t / weren’t提问.如 She must have been here yesterday,wasn’t she?/ You must have met her this morning,didn’t you?
b.若没有表示过去的时间状语,则疑问部分用haven’t / hasn’t提问.如 He must have been to Beijing,hasn’t he?/ The dogs must have eaten the food,haven’t they?
你懂了吗?欢迎追问.
希望我的回答能够帮到你,

一个是情态动词的反义疑问句 一个是虚拟语气

第一个也可以用didn't. 两句一样的,个人意见哈。
