Responsive/Mobile – Portfolio – Navigartion

The navigation on my mobile portfolio seems glitchy.

I have four portfolio items set up on seperate pages like this: https://christinalakeviewmotel.ca/portfolio-item/standardqueen/

When I view the mobile/responsive site on my phone, I can usually jump from navigating the pictures with either the arrows, or by swiping. However, it seems occasionally the arrows disappear and I can only swipe right – so I can no longer see previous pictures.

Thanks in advance!
