Excluding items from Smartcrawl sitemap

I want these off the sitemap…

?mg_item_categories=built-up-felt-roofing-2

?mg_item_categories=pitched-roofing

?mg_item_categories=polymeric-single-ply

?taxonomy=nav_menu&term=premier-roofing-menu-structure

?taxonomy=nav_menu&term=top-bar-menu

but in reality, nothing prefixed with ?mg_item_categories or ?taxonomy should be on there

Tried adding nav_menu to the taxonomy exclude option, but it doesn’t save.
