The evidence you posted doesn’t support your claim. For Network Extension providers there is a single Network Extension entitlement, com.apple.developer.networking.networkextension, whose value is an array of strings. Each string identifies a specific provider that’s supported. The screen shot you posted shows that the profile has the Network Extension entitlement but doesn’t show its content, so it’s impossible to tell whether it’s doing the right thing or not.
I recommend that you dump the profile’s contents to see what’s actually in there. TN3125 Inside Code Signing: Provisioning Profiles shows how to do this.
