I have essentially the same values as you and it works fine:

Have you tried variance 128 as Cagri suggested ?

I was doing a practive lab and was stuck with this. I have topology above.
It is all running eigrp. I want to load balance traffic 5:1 via R3:R2. I
have calculate the delay a nd applied the appropiate delay.The Eigrp
topology shows right metric as shown below. but the routing table does not
show the route. See the sh ip eigrp topo on R1. The ratios of metric is 5
(15132160/3026432). The routing table only shows one route. I am not sure
what the issue might be.
