Orders not being filled that match

I have created sell orders to match buy orders from xtroptions.gold to xcp. When I match with a sell order the matching buy disappears from the list but my orders always seem to expire after 6 days? What am I doing wrong? I have matched the orders exactly…

Update: I still have 5 sell orders that match 5 buy orders that look like they are going to time out in just a few hrs. I’m beginning to think that the only one who makes anything here is the miner! I sure hope other people have had some luck with the market place…
