404 missing images on Masonry layout

Hi, thanks for your plugin.

I have the following issue when displaying the masonry layout :

Some images (not all) url is broken (404 error). The img src is like “/uploads/2021/09/IMG_5856-800×842.jpeg”.
The image “/uploads/2021/09/IMG_5856.jpeg” exists in the upload folder but the -800×842.jpeg did not exist.

In basic “grid layout” the problem did not appear because all URL are like -375×375.jpg.

How does the masonry layout get image sizes ? Do I need to regenerate the thumbnail or something similar ?

Thanks !
