Urgent Salemaker problem

I have qty. price breaks on all products, which by itself works fine. I have implemented a 15% off sale, and it is applying correctly to quantites in the lowest price break only. It reverts to regular pricing on qtys. above the lowest break.
Products priced by attibute is set to NO.

This can most easily be demonstrated at this product:

• Add 1 item to cart. 15% sale calculates
• Change qty. to say, 40 (2nd price tier)
  The price does not reflect the 15% off anymore

Any quick help would be appreciated, as it is a major snag for me.
Thank you in advance!

Bump! Anyone have any ideas? I'm really disappointed that the salemaker is not working. I tried every option and combination of options in the product price manager. Hard to believe Salemaker won't function with quantity discounts, and I sure hope it's a setting I need to modify.
Thank you

Experts? Anyone? :)
