Plugin conflict with Discount Rules for Woocommerce

This plugin seems to conflict with the Discount Rules for Woocommerce by Flycart. When using bundle discounts (for example “2nd product 50% discount for selected products”) the last item in the cart that matches the discount rule is split up into 2 lines: one with and one without the discount, rather than calculating the discount on the entire order line.

If we remove the second line and add it again, the discount is calculated correctly on the previously-third line, and incorrectly on the last line. So it’s not a product or discount rule issue.

After disabling the PixelYourSite plugin, the discount is calculated correctly over all products, without splitting the final item.
