Rally Team Board does not filter archived cards when Timebox selected

Products

• Rally SaaS

Issue/Introduction

The Rally Team board has a feature to filter out cards in the last flow state using the "Hide cards after n days" option as shown below

However, when a Timebox filter is selected, all archived cards for that Timebox type and period show in the last flow state column.

Resolution

This behavior is working as designed.  Clicking on the ? icon after Archive Cards will reveal a popup describing this behavior.
