In subscription retention chart, I found the increase of subscribers count compared to previous month.
As you can see the screenshot below, the number of subscribers who continues for 5 months is 4. But the one who continues for 6 months increases to 5. What happened here?
I expect the number of subscribers is only decreasing, never increase.
Thank you for any help in advance.
