DSW changes switching from heart rate to pace

F7 Pro Solar. Today, I noticed something strange. I set the Daily Suggested Workout (DSW) based on heart rate.

Today when I woke up I had moderate training status “listen to your body” due to unbalanced HRV. Recovery time was 0 hours. I haven’t trained for 2 days.

Later, around noon, I headed out to work out. No stress this morning and no prior activity. 
The body battery was around 60

DSW just before starting the activity was:

Today: base 30’

Tomorrow: base 30’

Day after tomorrow: Recovery

Day after: Tempo

Just before pressing the start button, I went into the settings and changed the DSW setting from heart rate to pace just to have a “target” in mind for the first 10-15’ of run where the heart rate would be very low.

When I went back to the DSW the today and rest of the week DSW changed to:

Today: base 46’

Tomorrow: base 30’

Day after tomorrow: 39’ Threshold

Day after: base 30’

Then I switched it back to heart rate based and the “new” DSW remains.

Has anyone else ever experienced something similar?

It is quite odd because if there was a need for a training change since what I got a few hours earlier in the morning it should have been changed also without prompting it. If I hadn’t changed to pace and back to heart rate I would have stuck with the original DSW and I don't know what would have happened to the upcoming day's DSW.
