If you don't have IPv6 activated, you can't drag an object that uses v6 into 'Local Networks'. I just tried this with the "Internet" object and had no problem, so you may need to use the "Internet v4" object.

Thank you very much, this worked. I followed all the steps you advised below:
I am now able to access the internet through the vpn with the proxy server settings configured on the clients machine through gpo, also I have access to all internal networks, the only issue I am having now is that I am not able to access external networks
I have given users access to Internal Sites, Internet IPv4 and ExtraNet-Networks, but when trying to connect to sites/applications that go through the extranet it is not working. Any suggestions would be great.
ExtraNet networks our External networks we have access to from a different company.
I was able to resolve the issue this morning I haven't had a chance to revise my post. The resolution was to create a second masquerading rule for VPN Pool SSL -> ExtraNet-Networks, it is now working perfectly, thank you for all your help.
