Slow Sync After Factory Reset (F6XPro)

I backed up my settings, locations, everything, even the Activities folder, and then did a full reset. Afterwards I merged all the files back.

My watch DOES connect to my mobile and appears to sync, but it is running SO slowly. It will take hours for the sync to run. Why is this? Everything was restored back onto my watch. Is it trying to download all my workouts again from Garmin Connect on the web, or something else? Is it just a 1 time problem? Before the factory reset syncing was super fast.
