I had exactly the same problem.
I solved it quite simple: Go to System / Gateways and add a new Gateway. Choose any private IP that you like, its really not important which one.
Then check both "Upstream Gateway" and "Far gateway" checkbox, and select the Wireguard/Mullvad Instance as interface.
Add firewall rules to and select the gateway there for the hosts you want to be routed over VPN.
Thats when it was starting to work for me.
