Screen Number different in Abscence Screen

Experts,

We are getting a different screen number in IT2001 - Screen Number 2000 but in the configuration we have declared it as 2001.

Below are the screen captures for the same.

Configuration under node - Time Management - Time Data Recording and Administration - Absences - Absence Catalog - Determine Entry Screens and Time Constraint Classes

Any idea/thoughts why is this discrepancy.

Thanks,

Sriram
