How much data did you import?
How many BT (breakthrough) events are indicated within the last 90 days? See circles (size and color matters) on your XPMC chart under Progression tab.
You need enough data points expressing your max performance under fatigue to establish a starting signature. You can alternately adjust signature manually to a ballpark range as you have done then prove the numbers in the future with some BT efforts.
Difficulty of workouts (diamond count) is tied to your TL (training load; stars count), calculated form (fresh to tired), program type (TED, Continuous. Challenge), and Athlete Type (focus duration).
You can control intensity based upon the selections you make and what filters you apply. For example, changing duration based on your schedule or difficulty based on how you feel today or opting to ride outdoors whether solo with a focus duration goal in mind or a group ride at whatever intensity that involves. Your outdoor rides are quantified by difficulty, specificity, and focus.
