Even when working on a single column layout, with no multiple columns in the document this happens. It means that without selecting the 'Span fn across columns' option the footnotes appear at various places in a page.

We should not have to select this option for a single column design.

It also seems to add extra spacing below the paragraph, even if the option is selected. As if the spacing is created for the fn, even though it now appears at the bottom of the text frame instead of after the para!

This is using v 15.0.1 x64 on windows.
