Unable to Customizing Your Favorite Activities List

Device: Fenix 8 Dual Power

Watch Software: 22.35

Garmin Connect iOS: 5.25

I am trying to remove a particular Activities from the list but there is no options to do it from both the watch and the app.

I have read the manual and it does not show the same steps or options

Appreciate if anyone can guide me to the right direction.

Thanks in advance.
