Tablesorter and Multi-Column Sort

Tablesorter and Multi-Column Sort

Use the Tablesorter.js plugin and it works great, except the multi-column sort does not work. The arrows change and it doesn't throw an error, but it also is not sorting the column. I've checked and rechecked the code, but I also noticed the example on the site is also not working for that feature. Anyone else experiencing this?
