I have three routers sending Netflow data to PRTG. The Top Talkers list shows the combined Netflow data of all three routers. How do I see a Top list for each individual Netflow router?

Hello, your should configure three different NetFlow sensors with distinct receive UDP port on them. After that direct each router netflow to his port. Here example from Cisco router

flow record StdFlow
match ipv4 protocol
match ipv4 source address
match ipv4 destination address
match transport source-port
match transport destination-port
collect interface input
collect interface output
collect counter bytes
collect counter packets

flow exporter PRTG
destination 192.168.168.17
source Loopback1
transport udp 24061

flow monitor StdMon
exporter PRTG
cache timeout inactive 60
cache timeout active 60
record StdFlow

interface GigabitEthernet0/0/0
ip flow monitor StdMon input
ip flow monitor StdMon output
