I can't open the whole pdf. The bottom of the page didn't show up.

Are you able to share this pdf, so we can have a look at it?

Are you sure the scan isn't simply cut-off before the bottom of the page?

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
