Hi @Hsaniba,
Thank you for your reply, and I apologize that I misunderstood your question before.
The reason for this issue is that this option is selected by default when we give permissions to a folder:
This option causes child folders to inherit the parent folder's permissions, even if they break them.
You can make all folders revert to inherited permissions first, then break the permissions. Finally, uncheck this option when setting permissions on Apparel.
Reference: Sharing SharePoint folder items with unique permissions.
