Help with removing duplicates in the BCD

Somewhere along the way, I have inadvertently created too many entries in the section labeled "Firmware Application (101fffff)".
This is making the loading of Windows very very slow.

I have 365 items listed when there should normally be maybe 4-6 entries. How do I go about getting rid of the duplicates?

I have attached the dump using Bcdedit /enum firmware > enumfw.txt.
Any assistance would be greatly appreciated.
