Display the product prices by the selected quantity

Hello. Thank you for the great plugin.
Question is: When “Display the product prices by the selected quantity” is enabled, if you do not change the quantity on the product page, the price is empty, but after changing the quantity, everything works well. Can you tell me how to fix it?
