BusinessMind's lists are not actual lists. BusinessMind populates the drop down lists by all the existing values that have been utilized in that list based how its been utilized in a specific time frame. This means items that are not used in the list will no longer display after a certain amount of activity. In addition all lists in BusinessMind are stored in cache for faster loading. This means adding to a list may take a couple hours before it displays in the list.
The Model Tracking0, Tracking1, and Tracking2 lists are still controlled from the backend as per this article.
