Help I cannot figure out why my skinning knife is being mailed away when i put it on the do not mail list ?  what is going on? (TBC wow)

Hello, do you have used upper/lower case? Can you share your log?

is it case sensitive? I think i also had issues with items on 2nd line being mailed, for instance, i moved skinning knife to 1st line and it did not get sold but the food did. but perhaps i didnt capitalize the name of food. 

thanks for the help by the way >_<

it seems only the first item doesn't get sold >_<

Do you use wow addons? if yes try to disable all
