Disappearing course points/waypoints

I have a route created on Garmin Connect with 93.2Km (see https://connect.garmin.com/modern/course/25133309). I marked 13 waypoints along the route to mark relevant reference places, summits, etc. While this detail is irrelevant, my waypoints are at about Km 2, 8, 16, 18, 25, 27, 35, 38, 43, 46, 59, 64, 68. This is mostly a road course.

Since I know pretty well the area, I just want follow the course and I do not want Turn By Turn navigation, so it is switched off, as well as automatic recalculation. But I want to have an accurate "distance to the end" and "distance to the next course point".

When I load the course at my departure point, I go to the course point screen and I see the 13 course point clearly listed. And when I start the course, the distance to next course points displays accurately the (decreasing) distance to the first point, about 2Km away. However, a few hundred meters later, the distance to the next course point jumped to course point at 25Km. I go to the course point screen and the first 4 course points disappeared. A few kilometers later, without any apparent reason, the next course point is already at Km 43, and well before 20Km are made the "next course point" was pointing to the course end at Km 93.2. Note that I never went off course, neither I never got a "off course" warning. Since I am cycling at reasonable speed, I am not sure when the waypoints disappear, but I noticed that, in some cases, the "distance to end" flashed (went blank by a few tenths of a second), but I am not sure if this coincided with the "disappearing" waypoints.

While I am listing a very specific example, in fact the same happened to me all times that I used the 820 in the last few months. I never was able to have the course points working, which are a very relevant feature to me.

I am quite frustrated, since this mode was my main use of my edge units. I used this feature without any problems with the 800, Touring plus and even the 820, at least up to firmware 3.2. I am not sure when this feature stoped working, since I was almost off cycling from November 2016 to April 2018 for medical reasons, so I skipped several firmware versions. But I have reasons to believe that it was still working on version 9.0.

Any hint regarding how to solve this issue would be welcome. Since it may be a configuration problem, I list my relevant settings below. Am I forgetting anything relevant? Thanks in advance.
