I would't say misleading for now but I think you guys are in a rush to reject & complain.
Give it some time and go through it again. I had similar impression at glance. I had second thought after reading page 7 first paragraph, page 18- 6.4.1,6.4.2, and 6.4.3.
Your concern on page 26-9.3. Could be with Djibouti, Sudan, Kenya and Somalia. There is no as such legal boundary with Eritrea so article 9.3 page 26 does not apply. Remember they are rejecting the Algeria’s treaty as is.
