Client can't click but can hit on RunOnServer RPCs

Hello everyone,

I have a question about click and hit difference on clients for RunOnServer RPC events. As seen on my BP’s screenshot I created two custom events to call in game. One is a RunOnServer event and calls to the other one which is a Multicast. Ofcourse server can call the event but Client can only call these events when he hit it. Client clicks get no response. Is this an issue or a regular behaviour of UE4? And how can I make a client to allow click it? I also tried this system with collision events and they also work for clients. I mean, I can turn on/off lights by BeginOverlap and EndOverlap events with clients on all players’ screens. But why my clicks don’t work?

Oh and also keyboard input events (like a key press) don’t work in this situation for clients.
