Remove CA certificates from a Certification authority

Is there a way to remove CA certificates from a Certificate authority? It

looks like the person before me was having real trouble setting up the Root

Certificate Authority. If I go into the Certification Authority (Local)

->Properties -> General tab.

I see this

Certificate #0

Certificate #1

Certificate #2

Certificate #3

Certificate #4

If I view the certificates it looks like #0 will expire in 2029 and #1-#4

will all expire on the same date in 2031.

When I go into the certificate snap-in under trusted root certification

authorities it see all of these certificates with the same Cert Auth. Do I

really need all these Certificates? How do I remove #1-#4?

Thank you
