Forward Management Pittsburgh - Rent Overcharged?

In November, when I received a call from the Forward Management office manager about how my rent wasn't actually past due, she informed me that my rent was actually $690, instead of the $680 I had been paying so far.

Now, if you read my lease renewal for 2010-2011 (below, from 4/26/10), you will see that my net rent is $680, and that if I am not already paying $10/month for trash removal, that my rent is increased by $10. This is ambiguous, as you will see in a moment.

Now, my lease renewal letter for the 2009-2010 year is pictured below. I was paying $675/month for the 2009-2010, which included a $10/month trash removal fee. So, basically, the new lease agreement changes for 2010-2011 are completely ambiguous. Do I owe $680 (because I've already been paying $10 for trash removal), or do I owe $690? There really should be a final total rent amount on the lease renewal, so the average person can figure out how much is actually owed.
