Secure folder contacts visible in my car

When in my car, and my Galaxy S8 is connected by blurtooth, and I bring up the telephone directory on my car display, I am simultaneously seeing both contact lists from my phone - the secure folder contacts and the S8 default contacts. Even though I have the Secure Folder locked, still the contacts in which should be hidden in my Secure Folder are being displayed. Already I have changed Secure Folder setteings to NOT store contacts in Phone. Any advice?

Have you been able to find a fix for this? I'm running into the same issue and Samsung's support has not been helpful at all.
