use Garmin and Mywellness/Technogym at same time > data conflict to Apples health app?

All,

This week I started at the local gym. They have all Technogym equipment so I created an account at mywellness. Most of the exercises (not all) in the gym will be registered in that account/mywellness app. At the same time I also use my Garmin watch. The Garmin connect app registered all my activities, heartbeat, distance, steps etc etc. Both apps are connected to the standard health app from Apple. Question: will there be a data conflict when transferring the data from Mywellness and Garmin to health app? I can imagine both apps will not give the same data doing an exercise.
