Saved ride does not match finished totals

I went for a quick spin this morning on zwift and completed just over 11 miles this morning (in 40 minutes). However, when I went to the companion app later, it says I only accomplished 6 miles in 20 minutes. How can I get the correct data logged?

I am having the same issue with my last two Zwift workouts. Lost the last 16 minutes of today’s workout and last 45 minutes previously. Only capturing the first 30 minutes of the workouts?
