HTML won’t validate on specific image size

Trying to validate my page and we use SiteOrigin Widgets Site Origin Image all over the site and it’s fine everywhere EXCEPT when we use a smaller width file(?) The error is saying “Error: The sizes attribute may be specified only if the srcset attribute is also present.”

Our img html “”

Not sure if it’s bc it’s a png or it’s smaller in size but there is no srcset tag like there is here:

Might have to change the page but still want to know. I ran into this once before. Not sure what if anything can be done? It’s the Addiction Logo. I might have to replace it with plain html before you get to it.

Thanks for the awesome plugins. I use PageBuilder on every site I make without fail.

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