Avada image size autoadjust bugging images

Hello,

My website https://www.renovaliaenergygroup.com/what-we-have-done/ have been showing images cut in sliders recently.

I’m using avada 7.0.2.
If I set the size of images in containers to “fixed”, then they will show uncut but in a really small size.
The funny thing is, when accessing to the website as a “normal” visitor, and toggling the slide images, after a couple or three toggles, the container resizes to the proper height and width.
And for the fun fact v2, the first 3 or 4 containers of the webside load properly 100% of the times, it’s the ones below 4th section the ones failing to do so.

Thank you in advance for your help,
Kind regards
