Widgets/templates

Hi all

Im a bit stuck
On my pages when i open them it says theres
Your theme has 7 other widget areas, but this particular page doesn’t display them.

This is on all my pages so im editted some pages with wo bakery but unable to add any widgets to my pages from the demo import.
I wish to install a donation plugin and add to my homepage to the right side under clans list block although this is a block off wpbakery

Also on the pages it has the option temolate: eg clans page. I dont understand what these do?

Thanks
