How to clean up BCD entries? Rebuild the BCD?

This is normal that under Recovery Environment, The letters are re-assigned. This is why you have to be careful and select the correct one.
@dictum
Advice: Never use Easy BCD with Windows installed using GPT disk. Use Easy UEFI instead provided you know what you are doing. Easy BCD only works with MBR disk type.
Base on the screen shot above. Your disk 0 is your new Windows and your disk 1 contains the old Windows. Disk 3 contains a 512MB Fat32 partition and I don't know what that is. I suggest you disconnect disk 3 for now before proceeding.

Let rebuild new BCD's for both disk 0, and disk 1. Please follow step by step on the 2 screen shots below. On step 3, write down the drive letter for PM981_New. In the screen shot, My Windows is still assigned to C but it might be different from yours. In step 10, if the drive letter is different than C, then use the letter in step 3.

Do exactly the same for disk 1, this time select disk 1 in step 4 and assign letter V in step 7, Use V and the drive letter for Old Windows in step 10. This will create a new BCD for PM981_Old and you will be able to boot separately from boot menu.

From boot menu, select which one to boot from.
Once booted into Windows. If you wish, you can set up dual boot for Windows old & New. Under This PC, look for the drive letter of the offline Windows and type:
bcdboot X:\Windows where X is the letter of the offline Windows
