Group rides not group rides

Weird problem. My gps track, as displayed in Strava, is always 30 seconds to about 1 minute ahead of the other people I ride with. Makes it look like I’m riding off the front all the time. Some of my group rides don’t even show up as group rides. Just me riding ahead of them. New Wahoo Bolt. Using Wahoo app then upload to Strava. iPhone 16e. Ideas?
