Rails not changing direction if there is another railway behind the switch point

The bug

Flipping both switches, I would expect both rails to change direction, but the result is shown in the second picture, the left one is still in the old position, probably because there is another rail right behind it. The other one just switched fine.

How to reproduce

There are two screenshots attached, that are describing this problem better than I can. The first one shows the initial situation. Both levers are up and both rails are directed to the left.
