fixed menu – section height 100% – missing distance at the bottom of the section

Hello again,

when we build a page with several sections with 100% height
– with this small arrow that points down to the next section – 
we can scroll from one arrow to the next arrow.

but when we choose a fixed main-menu, e.g. with a height of 60px
(enfold > Header behavior > Sticky Header)

and then click on one arrow,
the section scrolls up to the bottom of the main-menu,
and with this the last 60px of the section – and so the next arrow – stay below the bottom of the viewport,

is there a way to fix this?

– CSS: section height is something like height 100% -60px ?
– JavaScript: change the offset of the waypoints?

Regards
