The people who check that may be the same ones who were previously bitten by the bug?
I always check the orders on my commodity market - specifically because i dont want to sell stuff that i dont want to sell.
And no, i'm not affected by it because i always keep my docking permission restricted when doing Trade CG or when i'm involved in manipulating the commodity market (and not the least because i learn from other's people experiences

)
And the easiest way to do it is obvious in the Commodity market itself.
Do i really sell something? Oh no, it's my previous Palladium sell order!!! (and this is actually when the
bug gets nasty: when you find out you have 10 sell orders and you really cannot remember what you were selling, but there is a certain txt file that can be checked, see below)
And if you think about it, it may not even be a
bug - it may be a feature, but a feature that is not made very obvious by a missing sign when the stock for the respective sell order get to zeroed.
If i'm a miner that sells LTD or Platinum or whatever, it's very convenient to be able to set a Sell order once, then only to resupply the stocks and have the sell order kicking in automatically
So yea, for me it's not necessarily a BUG, but a
bug
And the sort of elegant workaround, a quote from a previous thread where apparently Support said it's not a bug, this is how it is intended to work (sell orders are not automatically canceled)
On PC, outside of the game, the "market.json" file in the journal can tell you which commodities are still on export. They have a non-zero "BuyPrice" but zero "Stock".
(anyway -IMO- the OP should open a ticket anyway, maybe FDev will update the carriers commodity marker so it permanently displays the Sell order, no matter the stock - as it actually happens with the bar-tender_market which seem to work properly in this regard)
