Run labeled as Triathlon - cannot see in Connect and not sent to Strava

Using 17.75 and just been for a run. Ended and I noticed it didn't sync to Connect, Strava or Training Peaks.

Looking at the activity on the watch it has the 3 Triathlon rings above the activity - it shows the time ran and mileage but I cant do anything else with it. I've never used the Tri option and it's not even in my activity list/favourites. Running is right at the top so it's pretty hard to get it wrong!

Does anyone have any ideas what may have happened and if I can find the activity?
