Assemblie seems to mirror inside corridor

[cyberflow]

Hi there,

I was fixing up bowties on my corridor and noticed that i've got a little portion of my assemblie that seems to mirror at a certain station : 

And in section editor all seems to be ok :

At the first section theres a double of the assemblie : 

Anyone knows why it interacts like this ?
Anyone has an idea how to fix ?

Hi there,

After investigating i noticed an over on the 2 curves that created an overlap on the geometry 

Haven't tought of that point
