how to delete all activities for sale

I want do sale my Vivoactive 3 but cannot reset my data on the watch. Reset to default should have two options in the menu

1. Hold the touchscreen.
2. Select Settings > System > Reset.
3. Select an option:

   • To reset all of the device settings to the factory default values and delete all user-entered information and activity history, select Delete Data and Reset Settings.

     NOTE: If you have set up a Garmin Pay wallet, this option deletes the wallet from your device.

   • To reset all of the device settings to the factory default values and save all user-entered information and activity history, select Reset Default Settings.

I just can choose the second option. First option does't exist.

BUT current OS version 7.20

thx in advance
