Why Teamboard Columns and Cumulative Flow Diagrams don't match

On the Team Board page, the values in the columns and on the Cumulative Flow Chart are different.
The Cumulative Flow chart will only show changes made to columns within the last 30 days.
The Cumulative Flow chart was designed only to show items that have moved into a column in the last 30 days. Any items that were moved more than 30 days ago will not be included in the Cumulative Flow Chart.

For example:
You have 5 items in a column called Last

Team Board column

2 of the User Stories were moved to the Last column 3 months ago, and 3 were moved there 2 weeks ago.
Therefore, 5 items show in Last column on the Team Board, but only 3 show in the Cumulative Flow chart under Last.

As a workaround, if the columns have been modified in the past 30 days, and the Cumulative Flow chart is incorrect, then a hard refresh of the browser will resolve the mismatch.
