Junction/signal problem, trains wait on eachother (Solved)

ok, here are two pictures of a junction i have.
I followed Tutorial 3 and basicly this Junction is based on that.
However the two Trains on the left always keep waiting for each other, and once one of them turns around, only one of them will continue its track.

Can someone explain me whats wrong? or maybe explain the workings of the trafficlights? I think I got the theory of them wrong

Thanks in advance,

Each section of track is split up by signals. Each of these sections may only have 1 train moving on it at once. The left train wants to go down into the next bit, but the other train is already in that section! And visa versa.
You need to add more signals to split up the waiting area from the route going down the bottom left.
