Mass Teleport Casting Delay Issue

Trigger Action to Set Ability Real Level Field is not working for Archmage Mass Teleport - Data - Casting Delay [Hmt2(DataB1)]:

Ability - Set Ability: (Unit: (Triggering unit)'s Ability with Ability Code: Mass Teleport)'s Real Level Field: Casting Delay ('Hmt2') of Level: 0 to 2.00

In the object editor, Archmage Mass Teleport as a multi-level ability has a problem with setting Data - Casting Delay [Hmt2(DataB1)] for all levels except Level 1. All subsequent levels inherit Casting Delay from Level 1, regardless of the values set in these fields.
