Price Customization Not Working

I have customized the price of the products in the woocommerce-alidropship#/price tab of the plugin, however, I don’t think the price is working as the price of the products in the frontend is too outrageous, another thing I noticed is that the shipping price is not shown making it super difficult for me to manage. Your quick fix will be highly appreciated. the simple thing I want is that for any price btw 0-30usd should be incremented by only 20%, 31-200 by only 15% then others(default) should be incremented by only 8%
