Here is a picture of my issue:

What is happening? The top signal (last one in the depot) works like it should, but every other before that one in the same position says "cannot divide segments"
The space is identical in the working signal section and in the non working signal section since the same curve was pasted.
Expected for the signals to both have the same behaviour if the position and spacing is the same.

The rail on top collides with the rail below behind the signal point.

oh okay so the signal point is actually further back than the signal itself?
thank you for your time!
