This is a known issue.

Issue description

• You have permission to the share/folder as admin
• However when you go and try to access the folder in explorer, it gives a dialog to click continue to permanently get access
• This modifies NTFS permissions and adds your individual ID to the permissions.
• This can overwrite NTFS permissions so not a good thing.

Workaround:

Using PowerShell for example it is possible to get acl or delete any files or directories without adding your ID.
