No, as I said, only the Expense reports and Employees & Vendors roles were added.
It sounds to me like the app didn't install correctly. Can you please try and remove the app and reinstall it? To remove the app, go to Customize > My Account. Click "Remove App" for Method Expense Reports. This will not remove any data but just the screens and tabs for the application.
When reinstalling the app, pay particular attention to the area marked "Important" and ensure that all 4 roles are being created as "New"(see the picture I have in the installation steps at the top of this forum group). The only roles that should not say new are the ones that have already been created in your account, in your case Expense Reports and Employees & Vendors. Manages and Accounting and Admins should say "Create New Role" next to them.
Let me know how that goes,
