INE Vol 1 - Lab 21 - Question? - Controlling MPLS Label Distribution.

So I configured the following to limit the distribution of labels local to a router.

R3's Loopback is 150.1.3.3/32 and R6's Loopback is 150.1.6.6/32

#access-list 1 permit 150.1.3.3
#access-list 1 permit 150.1.6.6
#access-list 1 deny any

#mpls ldp advertise-labels for 1

But I'm still able to see labels for other prefixes...

Any thoughts on why this is? I even cleared MPLS LDP Nei * but still see labels for other prefixes...
