Question about Credit Card statement

Hey guys. Got a question about credit card statements. Is it common that transactions that happened during the last billing cycle to show up within transactions of the current one? Because for me now, this month's statement included one major purchase that should have been billed last time, but since it came up in this month, my credit utilisation crossed like 60%. I will be going to the bank tomorrow, had gone yesterday too, to ask why this happened. Few more details: billing cycle for my HDFC Freedom Card is 16th. The major purchase happened at 15th of last month. I had pre-paid a major chunk for that purchase on the same day (which is showing up as Credit on last month's statement) but that purchase itself isn't showing up in that statement. Any insight from some of the more experienced folks would be appreciated, thanks!
