regular & extend licenses - renew support price is not ok


I have bought 2 different licenses one regular and one extended of a codecanyon product.
When I click to renew the support for the regular licence which should be $4.13
I’m getting the price for the extended version $43.75 …

Typically extended licences imply a greater need for author support as you will be using the item in an expanded way beyond a single project. Thus the higher price for support.
