"Your theme has 4 other widget areas, but this particular page doesn’t display them."

Hey guys!

Am trying to get a basket/cart widget to show in my store. Am using WooCommerce, have added their handy sidebar plugin, created a new Widget Area exclusively for my store and have added my ‘basket’ widget to my widget area, but it’s not displaying on my store’s page.

When I click on Customise on my store page and click on Wigets, I get a notification saying: “Your theme has 4 other widget areas, but this particular page doesn’t display them.” How do I change this so that my basket widget shows??

Thank you so much to anyone who can help! Theme is Croma Music.
