Unlock Secondary Disk at Boot Time

I have Endpoint Encryption v10.3.0 and have my primary and secondary disk encrypted. I type my password before windows boots, my primary disk is unlocked and I'm logged on to windows automatically. However I then I have to type in my password again to unlock my secondary disk. For some reason, this prompt comes up twice.

Firstly, why does the prompt for the secondary disk appear twice?

Secondly, can I get my secondary disk to unlock at boot time in the same was as my primary disk?

I am the administrator of my machine, but not the system wide administrator for Endpoint Encryption.
