Hi,
Can you try copying the following file to your desktop.
%AppData%\Roaming\Microsoft\Network\Connections\Pbk\rasphone.pbk
Once on your desktop run the file rasphone.pbk which will launch the VPN connection software.
Can you see whether this software allows you to create multiple VPN connections and keep the settings.
If working, check back in Windows 10 and see if you can see both VPN connections.
Hope this helps!
I hope this helps. Feel free to ask back any questions and let me know how it goes.
