This is an accepted solution.
I would need access of your store to take a look into the issue. Without access it is impossible to suggest any solution as this is the default shopify section. So you can DM me your credentials so that I can take a further look and can suggest any solution on it.
You can add/edit/delete the sections in the Shopify theme easily by following below article from Shopify.
If you still facing issue then please send message to me.
