So, Bulk Shipping is not syncronizing with free shipping minimum order sum.
Let's say we have 1 product = $10
We use BulkDiscount Plugin => 10% discount for 2 products.
$10 + $10 = $20 - 10% = $18 correct? But if we added Free Shipping for minimum $20 => this order will still have free shipping but the price will be $18.
So Shipping option is looking for the "before" price and not the actual price after BULK DISCOUNT added...
