Wierd Rails Behaviour with costum stairs

[Anonymous]

I'm receiving a weird behavior of the rails with my stairs.

I don't really know what to do and how to adjust the rail so it will work

I think that the Problem is actually with the stairs when I create a random "normal Stairs" the railing works just fine. what should i do? 

here are some attachments to show better the situation.

thanks.
