If I may add more details about this,

The reason is because here within WordPress when an image is too big (dimensions) it gets resized and gets added -scaled in the name.

However, in Imagify, we create a backup for the non -scaled version while WordPress use the -scaled in the database and therefore, use it as a main source for this image.

So when the function https://github.com/wp-media/imagify-plugin/blob/2d98bbc79c1b633311334d084b8de0674353e5e8/classes/Bulk/WP.php#L181 tries to get the medias without webp, it returns something like : https://github.com/wp-media/imagify-plugin/blob/2d98bbc79c1b633311334d084b8de0674353e5e8/classes/Bulk/WP.php#L220-L226

And as the image with -scaled in the database does not have a backup file as we did a backup of the non--scaled version. So it lands into the 'error' => 'no_backup' section. Therefore, it is not counted nor optimized.

It may be fixed by https://github.com/wp-media/imagify-plugin/pull/811 tho as within this PR we add the generation of the -scaled version of the backup.

The following scenario fixed on 2.2.0.1: 1- activate imagify 2- upload small and large images => webP created 3- enable avif => generating is 0/2 on clean site

or

1- activate imagify 2- enable avif 3- upload small and large images => avif created 4- dsiable avif => generating 0/2 is displayed in settings
