I have a problem with my website, two pages work fine and the last only work sometimes. I know I can optimize the code to avoid some loops but it's not the problem, the code is in "defer". Actually images or some images get stucked in "pending" status. Here is the link to the page: https://www.rm-scans.ch/Services.html

It's really weird and I actually don't know what to do.

Thanks for your help!
