I recently added five items for trade to dispenser 28. These five items were Hitman's Heatmaker, Cozy Camper, Third Degree, Scorch Shot, and Rainblower. After making these available for trade, I noticed that I had selected "Single" instead of "Bag", so I closed the trade in order to change the trade from "Single" to "Bag". However, after closing the trade, my inventory only shows Hitman's Heatmaker and Third Degree, so I've lost the other three items. Any idea what happened?

Also, I found the descriptions for Single/Batch/Bag to be a little confusing. Sorry for the trouble!
