I paid $160 on credit card during a period. Today it said I owed $30 min payment and was late. Why?

I paid $160 during the statement period but today it was telling me to pay my minimum payment and that it was 4 days late. How could this be? Didn’t I already pay more than my minimum payment? It said it would only be $30 and the charge that went through the day before the minimum payment was only $68. My credit limit is like $300 and I always pay on time.
