incompatibility with clean commerce

Hello,
since last update of RGG, pictures don’t display at all..

I use RGG on different websites and I’ve noticed that the problem occures with the theme “clean commerce”.

the code appears but the gallery grid doesnt show up.
the link is attached.
the white spaces are where it was shown until recently.

Any idea of the problem ? (all my plugins, theme and WP are updated)
Thank you.
