Please help me why my order expired so fast

why is this happend ?
please , why they take it out of the list of sell and buy ?
why is it locked ?
why they took 2 mbtc for fee and there is no turn back ?

Default in Counterwallet is 1000 blocks (~1 week).
Can be changed under settings (see yellow arrows)

thank you JPJA
and If I click on cancel , what will happen ? do they send me that 2 mBTC for retrying another trade or I have to spend another Fee ?
