Adobe Zoom Problem

Hello guys and girls 🙂 I have a small problem and i hope someone can help me, i have been struggling for a while and its getting urgent. I have an adobe acrobat file and when i open with and turn on two page with scrolling like, i choose my zoom level to for example 75%. but i realize that when i navigate through the bookmarks that the zoom changes to for example 150% randomly, my question is does anyone know how i can make the zoom be the same (75%) when going through the file? I know that there is a setting on edit and preferences but this changes it only for me and not for other people. I have an old adobe file and in that file it works pefectely, the 75% zooom setting is the same when going through the page, both for me and another peron opening the file. Thank you so much in advance-
