This causes a problem on QtNetwork nm plugin. The QtNetwork implementation goes throught the connection list and returns the first connection that is set as default for for ipv4 or ipv6 as you can see on this code [1][2].
Since the gsm connection is always the default for ipv6 it will return the gsm connection as default connection even if you are connected over wifi.
