Variable product price does not appear after attribute selection

Please somebody help me, i have added a variable product in woocommerce as it should be, the dropdown attribute is there and the price range is there, but when i select the attributes, the actual price should appear right?
I’m using avada theme, and i have copied (update) the woocommerce template to avada’s woocommerce directory. I’m not sure if it is the compatibility of woocommerce’s version or avada’s or wordpress’.

Im using older version 4.4 because i dont want any issue with my theme after upgrading to 4.6
