In EIGRP I understood the routing table is built from the best route in the topology table. Please see details below:
Jul 8 13:19:15: %DUAL-3-SIA: Route 10.2.83.124/30 stuck-in-active state in IP-E
IGRP(0) 110. Cleaning up
GRLAGT2# ping 10.2.83.125
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.2.83.125, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
GRLAGT2#sh ip route 10.2.83.125
Routing entry for 10.2.83.124/30
Known via "eigrp 110", distance 90, metric 26885632, type internal
Redistributing via eigrp 110
Last update from 10.0.4.2 on GigabitEthernet0/1, 00:04:39 ago
Routing Descriptor Blocks:
* 10.0.4.2, from 10.0.4.2, 00:04:39 ago, via GigabitEthernet0/1
Route metric is 26885632, traffic share count is 1
Total delay is 50220 microseconds, minimum bandwidth is 100 Kbit
Reliability 255/255, minimum MTU 1500 bytes
Loading 5/255, Hops 4
GRLAGT2#sh ip eigrp top 10.2.83.124
% IP-EIGRP (AS 110): Route not in topology table
GRLAGT2#sh ip route | i 10.2.83.124
D 10.2.83.124/30
GRLAGT2#
What would cause a route to remain in the routing table and not be in the topology table?

You have made a mistake in the sh ip eigrp topo command. Check the syntax difference below.
This is exactly what you did:
R1>sh ip eigrp topo 172.31.24.0
% IP-EIGRP (AS 1): Route not in topology table
Like this it works as expected:
R1>sh ip eigrp topo 172.31.24.0/30
IP-EIGRP (AS 1): Topology entry for 172.31.24.0/30
State is Passive, Query origin flag is 1, 1 Successor(s), FD is 1280
Routing Descriptor Blocks:
172.31.11.2 (FastEthernet0/0), from 172.31.11.2, Send flag is 0x0
Composite metric is (1280/768), Route is Internal
Vector metric:
Minimum bandwidth is 1544 Kbit
Total delay is 50 microseconds
Reliability is 255/255
Load is 1/255
Minimum MTU is 1500
Hop count is 1
172.31.14.2 (Serial1/0.4), from 172.31.14.2, Send flag is 0x0
Composite metric is (1536/768), Route is Internal
Vector metric:
Minimum bandwidth is 1544 Kbit
Total delay is 60 microseconds
Reliability is 255/255
Load is 1/255
Minimum MTU is 1500
Hop count is 1
