How can i buy waystones with this shop?

So i was wondering if rolling maps myself or buying would be cheaper/faster and tried searching for waystones with 50-60ish rarity. Anyway, upon arriving on the tradesite i tried the usual thing i would do in PoE1, i set filters for iir and map tier on the left side of the panel under endgame filters... ... ... ehm why dont any of the filter options work??? tbf map tier works and # of revives kiiiinda works. it works as long as you dont set 0 as max value (looking for 6+ mod maps) ... cause then it breaks.

Try it yourself, open trade-> set nothing but map tier => only maps of given min-max tier are shown - set any value in any other engame filters -filter e.g. 1 as minimum or 99999 as maximum; (besides # of revives) and you get 0 results.

Soooo how do yall look for good waystones right now? Am i just doing it wrong???

PS: yes tried it ingame same issue
