Sourceset Responsive Image Problems

So I’ve enabled responsive images, and webflow output images:

Yet, I do not see the p-130x130q80.jpg in the code.

Can someone explain how this works? I don’t understand how the p-130 image can show up. Does this work only for webflow hosted sites?

Also, I can never see the smaller images being substituted on the screen. In testing, I’ve changed the content of the smaller images, but they never seem to show up.
