Problem with payment period

Hello. I have a problem with payment period. I had paid for Pro on 4 May 2016. But yesterday I paid again. Between May 4 and May 24 a not month, just 20 days. I don’t understand, what it was? It’s new rules, or system mistake?

@daniellakisza, could you have a look at this one please, just to make sure?
