Gallery not showing on AMP

Hello,

please, galleries (Final Tiles Grid Gallery – Image Gallery) are not showing up on mobile on any of my posts on AMP version of my page. It’s just white space. I checked two different mobile devices.

1.
Try to open my AMP version on mobile device:
https://www.google.sk/amp/s/www.foodfest.sk/cokoladova-torta-bez-muky/amp/
or
https://www.foodfest.sk/cokoladova-torta-bez-muky/amp/

2.
On the page with no AMP it works fine:
https://www.foodfest.sk/cokoladova-torta-bez-muky/

Is there any way to make my galleries work even on AMP version?
I already typed to Final Tiles Grid Gallery – Image Gallery support team but they said It is problem with AMP plugin.

thanks a lot in advance!
