Hello Sanpey.
Im try to remove all buy orders from market "Markets actions -> Delete orders -> Delete All Buy Orders" and then "Markets actions -> Remove Orders from CAT -> Delete All Buy Orders". They only dissapear from tab "Orders & Trades" but on "Market Explorer" and on web they still on. How to fix it?
What message did you get after triggered this action?
Did you select REMOVE or DELETE? Because DELETE is a real delete ACTION, REMOVE is only a remove by CAT structures not a delete over exchange.
