It seems the excellon drill files that is exported from Upverter does not handle the slots correctly, all slots in my project was misaligned in exported files, but normal holes appeared to be as they should.
Non plated slots seemed to be misaligned up to the right (attached image), and plated holes down to the left.
Drill files from my project can be downloaded here (files postfixed with “-fixed” are manually updated): https://drive.google.com/file/d/0B2V2uwrCfwEDdF9hLWJvQUdHUUk/view?usp=sharing
