Hi- I am having as issue with the spine receiving type-2 routes. The type-2 route for a connected host is present on the Leaf, but not advertised up to spine. Any help is appreciated.

Hello,
at first glance, you are missing 'ip pim sparse-mode' on the loopbacks of your spine:
interface loopback0
ip address 10.1.1.1/32
--> ip pim sparse-mode
!
interface loopback1
description ANYCAST-RP
ip address 100.1.1.1/32
--> ip pim sparse-mode

Your prefix list on the LEAF is wrong (or match statement in the route-map)

Hello desert7791,
I agree with Alexej
see the following section of first show output
>>Path type: local, path is invalid(rnh not resolved), no labeled nexthop
AS-Path: NONE, path locally originated
>>>10.1.3.3 (inaccessible, metric 4294967295) from 0.0.0.0 (10.1.1.3)
on the other leaf node you are not advertising the loop1 secondary address 10.1.3.3 in AF IPv4 unicast that should be your underlay.
The prefix-list LOOP needs to allow also 10.1.3.3/32 and must be called in the route-map named DIRECT-ROUTES-MAP
or you can simply use
network 10.1.3.3 255.255.255.255
in router bgp address family ipv4 unicast config mode
Hope to help
Giuseppe
