[SOLVED] Duplicate workouts virtual rides

I’ve always had 1 profile/activity type for bike rides, which included both indoor and out.
I have just created a new profile/activity type, specifically for Virtual Rides because I often forget to assign the correct bike to the indoor rides. Easiest way around that I thought was create a ‘virtual ride’ activity type and assign the bike I always use for indoor rides as the default gear.
Problem now is that every single activity I have done indoors has two workout builds assigned to it. I would rather not go back over 4 years of data to remove the second workout picture thingy!! See screenshot below. Any way to delete the 2nd workouts as per screenshot

Isn’t this the Skyline chart?
If so, you can disable

Ah! That makes sense. Thank you.
