请教 university Of arizona 成绩单的两个问题

寻梦季节

学校网上说关于成绩单的：
1、Each document is an original or a copy that is issued and certified by the university or college. It must contain the original stamp or seal of the institution and the original signature of the appropriate school authority. 这句话的意思是又要签名又要盖章吗？

2、Copies of original documents must be certified by the appropriate authority of the issuing university or college. Each page of the copy must contain the original signature and title of the school authority, the date of issuance, and the institutions original stamp or seal.
这句话的意思是成绩单每一页都要日期和学校的title吗？可是我开的成绩单是没有开具日期的。成绩单有两页，第二页也没有学校的title。
