How to resolve a bug of editing/viewing rights with XCarousel?

Hello everyone,

We are currently facing a very strange problem with our Intranet as the XCarousel Home section doesn’t show the “Top Carousel” that we have created when a non-admin user is connected and so the edit of this carousel is unavailable.

Also, when I want to create a new carousel with a non-admin account, when I click on “choose an attachment” it sends me to an error page with the text “You are not allowed to view this page or perform this action.”

So obviously this problem comes from rights settings but the actions that are forbidden for the account that is concerned ( a member of the XwikiHR group) are normally allowed in our settings :

Do you have any idea on how to solve this problem please ?
