The case-sensitive ordering results in all the Garmin devices that start with an uppercase letter to be listed first (e.g. Forerunner, Venu), followed by all the devices that start with a lowercase letter (e.g. fenix, epix, vivoactive).
This is surely not what a normal, non-technical user would expect or want this. Even a technical user would not expect or want this, assuming that they don't know or care which of the devices are supposed to start with an uppercase letter vs. a lowercase letter.
