When I sync data using my phone it is different than data from my watch.

When using a compatible Garmin watch with your Stryd, power and other run data are recorded by your watch. We recommend that runners use the app supplied by the watchmaker to sync run data (i.e. Garmin Connect). If PowerCenter is set up to sync with Garmin Connect, the data will flow automatically from Garmin Connect to PowerCenter.

Stryd also records your running data (up to 9 hours) on your foot pod. You can upload your Stryd data using the Stryd app on your phone. This will upload your run data to PowerCenter as well. This may cause your run to appear twice in PowerCenter. The data is very similar, but there can be small differences in data. This is because Stryd records data automatically as soon as the pod is activated, whereas your watch only records data when you start the watch.
