SimpleRegionMarket not rolling back Rents.

My SimpleRegionMarket not rolling back Rents, or letting players expand there rent 4 times. (As I has set.)

Anyone know how this issue could be happening? Here is my current config:

I would recommend submitting a ticket to the developer on the bukkit page.
