Remaining send keep counting


There is any way to only show how many mails remaining on status info?
In version 2.10 the number keep still and only update when send new ones. I attached images for better understand what I say. On 3.6 the count reduce to 0 and only keep “in progress”, when the cron start the task again (every 5min) the count starts.
