Dexcom G6 complications for Apple Watch

Hi, according to Dexcom's FAQs I should be able to select from 5 different complication styles. However the 3 I've circled below don't work on my series 5 apple watch (os 8.0.1).

Dexcom simply isn't listed as an option when selecting these complications, though it is available when setting up the other watch face styles.

Thanks for your advice!
