Pages moving left/right when scrolling up/down

Hi All, 

I'm using "Adobe Acrobat Reader DC" on my MacBook Pro '16 and am having a tech issue. When reading PDF files and scrolling up/down, the pages are also moving left/right. This is extremely distracting, and is making it hard to read the content. Is there any way to "lock" the page in the center, so when scrolling up/down, it stops moving left or right? Any suggestions on how to stop this would be greatly appreciated. Thank you in advance!
