For FRT21 and FRT22, the Days of Cash on the Forecast History slide (sourced from the error tab) and the Days of Cash on the Dashboard don't match. This is a bug.
We have decided to postpone the bug fix until FRT23. While the bug is easy to fix, repairing the historic forecasted days of cash and communicating with the customer is not.
