Folder configuration of gmail with alpine

I'm using my Google account with Alpine. I only appear to have the "Inbox" folder - I haven't got "Trash", "Drafts", "Sent Mail" or "All Mails". Does anyone have any ideas what I might be doing wrong?

Here my configuration:

Default Fcc (File carbon copy)    = {imap.gmail.com:993/[email protected]/ssl/novalidate-cert}[Gmail]/Sent Mail
Default Saved Message Folder      = {imap.gmail.com:993/[email protected]/ssl/novalidate-cert}[Gmail]/All Mail
Postponed Folder                  = {imap.gmail.com:993/[email protected]/ssl/novalidate-cert}[IMAP]/Drafts
Read Message Folder               = <No Value Set>
Form Letter Folder                = <No Value Set>
Trash Folder                      = {imap.gmail.com:993/[email protected]/ssl/novalidate-cert}[Gmail]/Trash

When you select your Gmail account there should be a list of folders, including your labels. In my config, which is more or less default, there is a [Gmail]/ folder. This is the folder which contains 'drafts', 'spam', 'trash' etc.
