Variation Bulk Pricing Not Working

Hi, I’m using ‘SOFT79 Pricing Rules for Woocommerce’ Version 1.3.1. I need to create bulk pricing(based on quantity) for each product variation and I’m aware that this plugin provides this feature. However, after I enter my bulk prices for a particular product variation and click ‘save changes’ (at the bottom of all the product variations), the bulk pricing fields become blank(reset). When I select this variation in the single product page, enter a quantity, and add to cart, it does not use the bulk price that I set for this variation at this quantity, but instead it uses this variation’s regular price(the default field). I have to enter the variation regular price, otherwise this variation will not be included in the single product page.

I have tried deactivating all my other plugins and just leave these plugins active:
Woocommerce
SOFT79 Pricing Rules for Woocommerce
WooCommerce Variation Swatches

I then repeated the process, from resetting the variation bulk prices to adding product to cart, and I still faced the same issue.

This problem has been there ever since I installed this plugin, so the variation bulk prices have never worked. However, I have tried to set bulk pricing rules in the ‘General’ tab of ‘Edit product’ (this applies to all variations under that product), and it does work, meaning that the calculations in the mini cart are based on the ‘general’ bulk pricing rules. However, what I really need is the variation bulk pricing.

Would greatly appreciate any help I can get!
