Why two Boot HD in EFI

When I boot and hold down option, I get two HDs to select from. Both are titled the same and both boot me to my OS. Is there a way to fix this?

Mac Pro, OS X Yosemite (10.10.1)

The old machine did this too, but I'm just now being concerned about it. I'm just looking to sharpen up the rough edges of my computer. I used migration assistant yes. When I got the computer, it didn't have the problem. After the migration it did. The other computer, which is a newer MacBook Pro, had the issue before. Then I wiped it and did a clean install, and it no longer has the issue. So it is something in the backup. I do not believe it has anything to do with hardware.
