Plugin works only for blog posts not well on normal pages, plus I can't copy/pas

I cannot make the plug-in work well. I cut and pasted text from Microsoft word with footnotes but I get classic cumbersome footnotes style (I get this [5], instead of the footnote being smaller and more on top and with no brackets as shown here https://www.ads-software.com/plugins/fd-footnotes/screenshots/). I have to manually enter the footnote to get the plugin style. Also, do you know if this plugin also works on non-blog pages, namely normal webpages? I ask because on normal webpages the footnote goes on footer of the page instead of the body of the page and makes it look very strange.

Any advice from anyone will be greatly appreciated.

Thanks
