Pagespeed Lazy loading

Hi,

Since few day’s, after 5.7 upgrade, I have the following problem.
1 image is not lazy loading anymore. Because I use auto optimize for this, my first question is here.

https://developers.google.com/speed/pagespeed/insights/?url=https%3A%2F%2Fweers.photo%2F

First image placeholder(bridge) is completely the same as the second one.
Creating a new page and placing one, now problem. Placing 2 it marks the second one in not having lazy loading. Also GTmetrix is coming up with that problem in lazy loading

Why or how, don’t understand and not getting it clear. Debugging with the template owner didn’t work.

The page I need help with: [log in to see the link]
