Salary not equivalent to minimum wage?

I am on $62,400 salary. Which would be $30 an hour for a 40 hour week.. problem is I work 55+ hours a week, should I wait and see if it balances out or complain?

I thought I should add more context, here is copy and paste of two parts of my contract I found relevant to the conversation.

Please give your feedback.
