Crumbreads and Sidebars

Hi Team

Crumbreads :
can you explain to me how to set up breadcrumbs in some pages ? can we put breadcrumbs page by page ? i selected in the enfold them + on each layout page i want but they dont appear. i tried to switch from transparent header to not transparent but it doesnt work either. I am sure there is a little thing to check but i miss it.

other point : Sidebars
my sidebars are not a straight bar as it is cut by page elements and the menu (sidebar widget) is always randomly located .. is there a bug with sidebars ?

tanx for your insights
