Multicast replication problem ( Event calls only 2 times)

I have BP Character, BP Component, BP Interface and BP Actor. Component, Character and Actor are replicated. I added Component to Char, and added interface wich returns this component. I added to BP Actor collision box and code on screenshot. MULTICAST function is function from component which prints hello in multicast event. If i call this function more than 2 times, the text will printed just 2 time. Why?
