Calender associated with task lost during copy

[0Lq]

MS Project 2010, Windows 2007. Project is set to save in 2007 format. Project is open and file is loaded. It shows (Compatibility Mode). Five different calendars are used in this project. All five calendars are shown in the Global.MPT.



I create a new project, and move all the Calendars from Global.mpt to the new project. I copy all tasks from the first project and past them into the new project. All the calendars for these tasks show "None." Expected behavior was the link to the calendars would be retained.

Any ideas?
