I have 70 stores that I track by the number we use internally (i.e. 02 - New York, 10 - Boston, 65 - Anchorage). If I try to add a task with Smart Add, the @ brings up the location list. I click on the location I want, but it adds the @ sign and the location to the text of the task, and does not assign the task to the location.

Other than that, everything is fine. I can manually add the location.
