The number at the top of the page shows the remaining number of “Today’s Lessons”. The max number for the “Todays Lessons” setting is 100. As you have done 5 lessons already, then 95 is the correct number to show. You can read more about “Today’s Lessons” here or in the original forum post here.
I originally thought you might be having trouble with “Today’s Lessons” but as you mentioned 50 items in your previous post and when I checked your lesson preference, seeing it was set to 100, I thought it might be something else. Could the issue you are seeing just be the result of the way “Today’s Lessons” work?
