Media issue

Hello,
I really liked using this plugin, the UI is great and it does provide great results overall.
There is one issue however with the lazy load in the media section. I want to exclude the logo from lazy loading so I tried adding the logo filename logo.svg to the exclude list and ended up with a broken image, I also tried adding the full url to the file, still broken image.
The src attribute is saying undefined.

I have the latest version of the plugin.
What should I do?
