The sorting by price-desc is NOT working correctly.it takes the price of a variable product with the price of an attribute.
for example please check
https://www.refurbishstore.gr/shop/server/dell-poweredge-r900-4xe72202-cores-16gb-perc6i-5xlff-2x1570w/
this product cost 502€ but with the extra option of its attribute it costs 1574€
so at the sorting it goes at 8th place of my shop! even if it shows correctly that costs 502euros
https://www.refurbishstore.gr/shop/?orderby=price-desc
that is wrong

But if you sort them by price / low to high is working fine
https://www.refurbishstore.gr/shop/?orderby=price

the same product is at the 22 page at 101 place before end (the highest price)
Can you understand the issues?

I don’t want to unhide the range of prices for my products.
the price of it is 502 and if you choose the extra setting it costs 1574, so it is correct that at the list of my products I have only the basic price.

so the sorting for price-desc must take the basic price, NOT the price of the variable products with attributes.

Any suggestion for that ?

thanks in advance
