Flowpaper CSS cluttering

I’m doing some spring cleaning on my website, optimizing things for faster page loading and such.

When performing speed tests, results are consistently showing that two CSS files associated with Flowpaper are systematically loading with every page, regardless of if I have a PDF file on the page or not. This means the Flowpaper plugin is slowing down each and everyone of my pages for apparently no reason.

Can anyone tell me if there’s a way to remove these text files? I’ll copy them below:
