Plugin does not correctly generate the srcset attribute

Hi, I would like to report a bug.

I’m using this plugin along with Jetpack. The problem is, the plugin does not correctly generate the srcset attribute. It makes my images that should be served using Jetpack’s CDN, it was shown using my original path instead.

More about this can read on this thread: https://ww.wp.xz.cn/support/topic/jetpack-didnt-served-my-images-with-its-cdn/#post-18596709
