When I run a bulk update of Jira tickets (changing labels), I can see that I am working with a certain number of Jira tickets, but when I confirm the operation, the number that the operation in progress screen shows is different. It doesn't happen ALL the time, but about eighty percent of the time the bulk-edit numbers are different.
Here are some screenshots...
In this screen you can see that I am removing labels from 220 tickets...

But after I click [Confirm] I see this...

What gives? Is this something I should be worried about, or is it just a bug in the bulk operation progress screen?
