Trade site price sorting bug

There's currently a bug on official trade site in which items sorted by price (cheapest -> more expensive) ignore the said sorting criteria.
Example: Price can go from 1.3ex -> 1.7ex -> 1.4ex
Tried clearing browser cache, sorting only by exalts instead of chaos equivalent but nothing works and you'll end up getting random results.

This is on many different items and below is a screenshot from Shav's
