Plugin delivering only one size of image

Hi,

I have tried every delivery method and nothing changed.

The problem is that only the smallest size of image is delivered and nothing else.
Every other needed size is generated in normal and 2x retina size and don’t know why it is not deliveing the retina.
The files exists on the server.
I use the plugin with WebpExpress plugin
So basicaly the size exists but it is not delivered.

Example:

x.pl/wp-content/webp-express/webp-images/uploads/2023/03/x-300×182.jpeg.webp 300w, x.pl/wp-content/webp-express/webp-images/uploads/2023/03/x-1024×620.jpeg.webp 1024w, x.pl/wp-content/webp-express/webp-images/uploads/2023/03/x-768×465.jpeg.webp 768w, x.pl/wp-content/webp-express/webp-images/uploads/2023/03/x-1536×930.jpeg.webp 1536w, x.pl/wp-content/webp-express/webp-images/uploads/2023/03/klinkier-alhar-2048×1240.jpeg.webp 2048w, x.pl/wp-content/webp-express/webp-images/uploads/2023/03/x-300×[email protected] 600w

I would really appreciate your help.
Thank you in advance.
