Sorting by price is (may be) wrong

The Trade site, at least the Standard, at least for normal Unset Ring item, lists items in wrong order.

Go to Trade, Standard, search for item "Unset Ring", Normal, "up to 2 months ago", click Search, click (two times) on the price (requesting to sort by Price, ascending), and (if it reproduces) will see the following order:

Unset Rings with price 1 Chromatic Orb;
Unset Rings with price 1 Silver Coin;
Unset Rings with price 2 Jewellers;
Unset Rings with price 1 Chaos Orb;
Unset Rings with price 2 Chaos Orb;
etc.

According to the the https://poe.ninja/standard/currency page:
1 Chromatic is far more valuable than 1 Silver.
Moreover, 2 Jewellers are valuable than 1 Silver.
