Reproduction Steps:
Create 4 folders (ie, "Folder One", "Folder Two", "Folder Three","Folder Four")
Delete "Folder Two" by from the contents view > settings > delete
Move an Inbox message to "Folder One"
That folder will be opened with the message contained
Move an Inbox message to "Folder Four"
Expected Outcome:
"Folder Four" is opened with the message contained
Actual Outcome:
"Folder Three" is opened with the message contained
What appears to be happening is the "Move Message" drop-down box is blindly listing the folders as numbers 1 through 4: "Inbox", "Folder One", "Folder Three", and "Folder Four" -- The problem is that "Folder Two" is number 3, "Folder Three" is number 4, and "Folder Four" is number 5 so the drop-down is misleading on which folder is being select (ie, I choose "Folder Four" but the drop-down assigns it to number 4 which is actually "Folder Three"). I tried to hack into working by editing the HTML to have the correct folder names, but the forums has input validation that rejects my edits and forces it to be between numbers 1 through 4.
