I've been experiencing the same issue...this was the response from tech support.
"As I understand the issue that since upgrading from 6 to 7, OSX now requires login twice with filevault2 startup volume, and takes much longer to boot.
I regret the inconvenience caused.
In order to resolve the issue, please follow the steps given below:
1. Click on Apple icon on Menu bar and select 'System Preferences'.
2. Under 'Personal' you can see an option 'Security & Privacy' click on it.
3. Select 'FileVault' tab there you can see 'Turn off FileVault'.
