Item page cannot view pictures more than 4 on PC version

I allow users to add pictures more than 4 in their listing.
After they submit 6 pictures, we cannot scroll to see the 5th and 6th picture on PC version, but we can see them all on mobile version.

Please help.
Thanks in advance.

Such listing does not exist.
Please reproduce issue on our demo site.

I'm sorry. I sent wrong URL. The right URL is: http://psayfree.com/cars-bikes/cars/rav4-l-2001_i92

I try to reproduce on demo site, it works. Sadly it does not work on my site.

Make sure you have latest theme version.
Try to uninstall zara configurator plugin.

I just bought the theme 3 days ago. It should not have new update yet. 

I uninstall the Zara theme, install it again. Same problem. Still cannot click view to next 5th picture.

I try to activate default theme, it works fine.

Conclusion: problem is really from Zara theme. I am absolutely disappointed.
