Not able to scroll past 2 photos on my product page

[Hey_Chips]

Hi. I am a user of Avone theme, but since I did not sign up for extended service plan, I am not able to report and fix this theme bug. 

I am hoping someone technically savvy can help me out. 

On our product pages, we can't ever scrolls past 2 photos. See https://heychips.com/products/corn-chips 

And after you scroll to the 2nd photo, you can't ever scroll back to any photo in the row. 

Checking the Avon theme demo, it should not have this issue. Not sure how I can fix it.

Please help. I will send you some free chips you way if you solve this for me. Thank you very much!
