My guess is that the problem is the box.
In the gro file you mailed to the list, there was no box.
If you use this file gromacs might generate a incorrect box.
I still only get one peak though and never at 135 degrees.
But maybe you have used a different box size.
g_sorient calculates the smallest distance using periodic
boundary conditions. So it could be that it uses an image
which is displaced in the y-direction. This answer could
(correctly) be 135 degrees.
The solution is then to use a very large box.
