How do I change the default activity type when uploading an activity from a device to Garmin Connect?

I have a Garmin Oregon 700, which I use almost exclusively for kayaking.  Whenever I upload an activity into Garmin Connect from this device, it uploads as "cycling."  I then have to manually change the activity type in both Connect and Strava (since I have automatic uploads from Connect to Strava enabled).

Is there a way to change this?  I also have an Edge 830 and Forerunner 45, and both of these upload with the correct activity types (cycling and running, respectively).  I can't find where this setting is configured.
