Local IPv6 still visible after disabling split tunneling on SSLVPN

[GHGIT]

I am trying to configure a fortigate to host an SSLVPN so I can get rid of our last Cisco.  Part of our company's policies is that we disable split tunneling.  When I did this on our old Cisco anyconnect VPN, when I connect to the VPN I see all my internet traffic pushed through our company network and "what is my ip" shows only the ipv4 shared address from the company.  Down in the tray, the icon says company.internal Internet Access and it says gstwifi no internet.  I think I have the Fortigate configured correctly but when I connect to it using forticlient, "what is my ip" shows the company ipv4 address but it also shows my local ipv6 address.  in the tray, the icon says company.internal internet access  and it says gswifi Internet Access.  To my knowledge that means I would still be at risk of split tunneling.  Any suggestions on what to check would be greatly appreciated.

Thanks for your help.
