Can't create mailboxes in iOS6 Mail

Question

I found the following in another thread, but it doesn't work for me. Don't know why.
Go into Mail app, click the back button in the upper left hand corner under you see all your mailboxes.
If its an IMAP account, you will also see a section under all your inboxes, go into there, and click EDIT.
Create anew mailbox button appears at the bottom (iOS6)
I have an iPad4 with multiple eMail accounts, some IMAP, one of them POP. Following the above instructions, there's an EDIT button to the right of the word "Mailboxes". Clicking on it it changes to "Done" but nothing else changes on the screen. Clicking on any of the right arrows next to any of the accounts produces an EDIT button that presents three buttons at the bottom, "Delete," "Move," and "Mark." The Move button gives me the option to put it in the Trash. I'm missing something.

To create a screenshot - hold down on the sleep/power button and while holding down on it - tap and hold down on the Home Button until you see the screen flash white and you hear the sound of a camera shutter go off. The screenshot will be automatically saved to the Camera Roll of the Photos App.
Let me preface my steps here with this .... Gmail on the iPad works a little bit differently than other email accounts. Gmail has an archive option for one. What I am describing here should work with an IMAP email account on your iPad.
Launch the Mail App and go to the Mailboxes view - the view where you can see all of your email accounts. Select your email account here.
In the next window - you should see an Edit Button at the top of the window next to the name of the email account. Tap on the Edit Button.
After you tap Edit - you should see a New Mailbox Button at the bottom - Tap New Mailbox.
The you will see a window where you can Name the Mailbox and Save the new Mailbox. Name the mailbox. You can choose the location of the new mailbox with some limitations - experiment with it and see what works for you. Then tap on the Save Button at the top.
When you are finished - tap the blue Done Button at the top of the window that you see in the 3rd screenshot.
