Garmin Training Load

I’ve started doing my TR rides outside again in the last few weeks now that the weather has turned. I have a Garmin Edge 820. I’ve noticed that my workout rides are no longer producing a Training Load/Status change within Garmin. I was having no issues a few weeks ago when I was riding indoors but now that I’m using my Edge 820 for the workouts, I’m having an issue. Last year everything was working perfectly. I’ve contacted Garmin and they have been slow to get back with me on this. Does anybody have any insight into what could be causing this?
