If you are using a service to restore Twitter share numbers such as "Newsharecounts" and your "Show share count minimum" number is not working properly and showing despite the threshold you have listed, this is being caused by that service and not BDOW! (formerly Sumo).
These services overwrite the actual number of shares you have and updates it themselves by "changing" the value. Unfortunately, their logic cannot see or listen to the share count minimum and displays it regardless of this setting.
