Backup Exec 2014SP2 only storing 1TB on 1.4TB LTO5 Tape??

I am replacing a Windows 2003 server with BE 2010 with a new server running Windows 2012r2 and BE2014SP2.  On the old server I can back up 2TB of data on to an LTO5 tape because of compression.  On the new server I have copied the exact same data from the old server and move the old tape drive over and now I can only store 1TB before it prompts me for a new tape.  I have hardware compression enabled on the tape drive.  Here is what the first tape stats look like:

Media Capacity:  1.39TB

Used Capacity:  1.39TB

Backup Data Written:  0.989 TB

Available Capacity:  1.85 GB

Compression Ratio:  1:1

What could be causing this?  The Drive is an HP LTO5 SAS drive on a Dell R720 server.
