Advanced Search 4 - Problem Product Price with Discount

[muzz-as]

Hello. I have Prestashop V1.7.6.3 and module AS4 v.4.12.9. 
The filter only works with the initial price and does not work with the discount price.
For Example: at first Some product costs $100, after that I make a discount $20 and filter cannot find this item if I set the values from 1 to 80. How can I fix it?
