Rent help!!!

I am a younger person and I know a lot about renting however, I want to make sure I am in the right!

When we moved into our apartment it was mid month and our first months rent was prorated! We paid this and then went back on at the 1st of June and paid a full months rent, again July 1st, and on the first all the way up till now! We were in a 6month lease and so we have paid may, June, July, August,September, and October! This is 6 months! We will be out by the first of November.

Our landlord is claiming we own another months rent but that would mean we are paying for November and we won’t be here! So has anyone had this happen? Do we owe this?

Our lease doesn’t say anything.
