Multiple Sliders on one page issue

I use multiple banners on a page (normally just homepage) for numerous websites and I have the same problem on all.

Basically the second banner doesn’t load, it shows the loading… icon and if you inspect it says could not load image. The image exists and is available if you open it from there. See the example website.

On a mobile sometimes all the banners will not load. Unlike the example I’ve given where it leaves the space the image would be, on a mobile there is no space left and no loading… icon.

I have the Pro version. Please please help as I am getting very frustrated with the lack of PRO support and need to get a couple of websites live that it is affecting. I have been unable to get PRO support help via the other avenues.
