In the Footnote options (Insert | Reference | Footnote), change the
"Place at" option from "Beneath text" to "Bottom of page." Click Close
to close the dialog box without inserting an additional footnote.
Already done!
OK... i uploaded two pictures:

this one show a wrong layout, where there is lot of space between the
footnote and the footer and between the body text and footnote
but in the same section of the document

in a page without footnote, everything is OK.
In the properties of the footnote style, the space before and after the
footnote is ZERO
many thanks
