Huh. Right enough. I forgot about the right-click option, I confess. I used the drop down menu of chests under the backpack. I will update the guys on this, thanks!
The Chest issue is resolved. I've tested it myself. The Invert request has also been actioned.

I was inquiring about when you highlight more than 1 item in your backpack and try to send to a specific folder, only one of the highlighted items get sent, not all.
