I wonder if there is some setting or maybe a corrupt profile at play here.
To test what a "default" install looks like, I did a backup of my current Thunderbird profile. I then uninstalled Thunderbird, removed my profile, and installed the current version. Version information shown in the picture Thunderbird Version
Once the install was done, I launched Thunderbird. I saw the screen shown in Picture # 1
Once I filled in my information for my gmail account, I clicked the continue button, and the screen was modified to what is shown in Picture # 2
I then hit the Create Account
button which caused things to run a bit (30 seconds I believe), and was then shown the dialog box in Picture # 3
I then made no changes, and hit the Ok
button, and Thunderbird loaded, and the screen I saw was in Picture # 4
As you can see, I only have an Inbox
folders under my e-mail account. I don't have other folders yet (Sent, drafts, etc). The settings that I have for the folders are shown in Picture # 5
But, once I start using it, those folders should show up for you under that one e-mail account.
So, my suggestion would be to verify your settings for the account, and if that does not work, backup your profile, and try a fresh profile.
Hope this helps.
