SSL VPN and Split DNS

Hello, 

I am trying to setup SSL VPN for our users but I am not able to resolve internal DNS names once connected. I have the SSL-VPN Portal setup with the split dns entry for my internal domain and DNS servers but when a user connects the internal DNS servers are put after the client DNS on the network adapter. I can ping internal resources using IP but not via FQDN. I have the dns suffix set in the portal as well. If I manually move one of the internal DNS servers up to the top of the list on the forticlient adapter after connecting then it all works properly but that's not going to work for everyone. Any help would be appreciated. I am using a Fortigate 200E on 6.0.4.
