Monthly Tape became Scratch Media

Hi,

I am new to Backup Exec 2010. For the past few weeks, I have just been exporting and importing Weekly backup tapes without any issues. Basically, importing OLD Weekly tapes from storage that are in an "Overwritable" state has been seamless. They become Weekly backup tapes again after import, retaining the original state they were in before the were exported out of the server.

However, when I tried to do the same for MONTHLY backup tapes, I noticed that instead of becoming MONTHLY backup tapes again after the import, ALL of them became SCRATCH MEDIA. What did I do wrong and how do I correct this?
