In my minecraft world. I have recently encountered a bug with train signals. It is displayed on the rails as, if there was a train signal there, but the green line shows that there is no signal because it goes through. I have already tried to reset the chunk to get rid of this bug but when I manually put a rail there again, this signal was back on the rail. I can also place a new signal or even a train startion over the signal. The problem I have is that no trains run over this signal automatically. The train can no longer find a path, only if I manually move it one block forward can it continue automatically.
How do I remove this problem?
