The vehicle probably came with Gracenotes with Sync 3.3, but not 3.4. Sync 3.3 is half the size of 3.4 and would allow the installation of the Gracenotes package. From the storage numbers above, you installed 3.4 on this unit previously and have downgraded the unit.
What are you trying to do? Do you want to upgrade to Sync 3.4? Stay at 3.3 with Gracenotes?
Maybe this will help…
