Windows 10: Bitlocker keys: Which one to delete?

I noticed that on my Microsoft account I have three Bitlocker recovery keys. Two of them on the account show an upload date, but the third one shows "Invalid Date". This is the current one. Is there any reason to retain the two keys that are not current or may I delete them?
Also, why does the current one not show an upload date?

:)

 

where to find bitlocker key?

The BitLocker key is in one of the three places that the program suggested to you:

• In a folder of your choice.
• Jotted down on a piece of paper.
• In your Microsoft account (if you have one).

Which one did you select at the time of encryption?

Did you create a backup of your data?
