Masonry grid bug since update

Since the update I have some issues with the appearance of my items in masonry grid.

I have a portfolio page with a masonry grid and a preview of some items on my home page.
This two masonry grid are set up differently :
– On my home page they were squared and with a B&W effect (and the color showing on overlay) in a automatic perfect grid. With the update some images didn’t show, randomly I think. And so I choose to keep the B&W effect but tried to change the type of masonry grid. And with the one you keep the same width for images without any resizing (Masonry flexible) it works : every image appear.

– On my portfolio page it’s also a perfect grid but manual. I have also a quick css to change the color of the overlay:

#top .av-caption-style-overlay a.av-masonry-item-with-image .av-inner-masonry-content:hover {
background: rgba(129,58,141,0.65) !important;
}

Every old images appear. But when I created a new portfolio item and : It’s blank on the portfolio page and it appear in the home page …

Help me please !
