You can put your BoB on hold without putting your shelf on hold, but if you put your shelf on hold, your BoB automatically follows. Makes sense, if one can't get to your books to credit order one because they are on hold, neither can a BoB transaction. They are probably either all still there or in your cancelled. Just send everybody a PM telling them you didn't realize it would do that, and that your shelf is off hold now, and if they are interested, you would like to go ahead with the trade.
