Issue with connecting to the guest network through one of the repeaters

I have a Wi-Fi network. The main router is a Speedster, and there are two repeaters connected to it, both Challenger. The repeaters connect automatically through capture in the main router’s admin panel. My question is: why does one of the satellites allow connection only to the home Wi-Fi network but does not allow connecting to the guest network? On the main router and the first satellite, both networks connect without any problems.
