These settings are optionnal in both HE and HA but HADB does set level. Since it is working in at the component level, the issue is most likely with the alexa skill in relation to hubitat. This may shed some light on that:
Anyway if you could show us the log when asking alexa for the CT, it would be very helpfull.
P.S. I'm a google home guy, I know nothing about alexa
