woocommerce help

Hello, Need someone to help me with adding correct woocommerce bulk discounts when a customer purchases 2 different products. See attached. Both products have bulk discounts of 3 or more sets of furniture. In the picture attached they are getting 10% off the order when they should be getting 12% as there are 6 sets in the cart.

Please give me a flat fee to fix/correct this issue. Please do not say HEY or ask my budget. Thanks!

Buy 3-4 and save 10%
Buy 5-7 and save 12%
Buy 8 or more and save 15%
