Multiple Instances of Universal Viewer Block on Page not Loading all Images

Hello, I have a student who built a page using the Universal Viewer plugin; they added five UV blocks on a single page. The images will load in the individual blocks SOMETIMES, and never in the same configuration. For example, all five images will load in all five different UV “windows” on a single page. The next time one reloads the page, only three will show. The next time a different three will show. Has anyone run into this problem before? It seems like one should avoid putting more than one universal viewer block.

There may be interferences between js. Which version do you use? In the last version, i integrated Universal Viewer v4 for Omeka S v3 and v4. Can you try it to check if it is fixed?
