Duo Windows Client hides VPN before login

We have recently rolled out Duo for windows login. The windows login function works great but we have notice a conflict with our Forticlient VPN client. We have forticlient connect before login enabled. Normally at the windows login screen below the username and password we had a button to connect to VPN before login. After installing the Duo client the button for VPN disappeared so we can no long connect to VPN before windows login. Uninstalling Duo brings the button back. Not even sure where to begin to troubleshoot this issue. It appears that the Duo client is changing something in windows to hide these options.
