Market Press Variations don't update

I want to offer discounts for purchasing multiple items. Your forums seem to indicate this would work in 3.1.1. It is not there...

So I tried using variations. I created an item with 3 variations S,M,L then published item.
It showed up on the item but when I went to add XL as a variation it never shows up. I tried new browser, clearing cache, different PC... Nothing worked.

I deleted the item, then recreated with different product name. Then went to add variations and the "old" ones show up! Can't clear them out of system. They appear "stuck" in your system some where.

Are you going to fix Marketpress to include discounts for quantity purchases?
Do you have another product or plugin to fix this?
