Comments not working in widget

Hi,

I am currently using your plugin, and it works very well! I have been searching for a plugin that could display one full post on a static frontpage and yours are the only one I found that actually work. I do this by running the “post list widget” through a widget on my static frontpage. But when I check “Display comments with the post?” nothing happens, even though there are comments with the post. See my frontpage here https://www.danicachloe.dk

Is there someway to fix so that it will show comments after the post? It is the only piece missing for it to be perfect.

I am running the “The Voux” Theme on WordPress 4.8.

Thank you in advance.
