Hello,
Sorry for misunderstanding. You just shared a video that is why from your video it seems you talking about public section.
I have seen your screenshot then I have test your site and notice that you contain CDN(Cloudflare) cache tool. Kindly flush the cache and I suggest you to disable those cache tools while your site is under construction.
In case after flushing cache. If the draft section “Brouillon” still display some number and not any item inside it. Then deactivate your third party plugins and then check back. This will surely fix the issue.
Best Regards.
