Is there a mistake in the sympy fourier_series?

Question

Good morning, I am trying to compute the Fourier series of f=x (periodic in 0<x<1).

I am looking at the example here: https://docs.sympy.org/latest/modules/series/fourier.html#sympy.series.fourier.fourier_series at the bottom of the page there is the following code as example

   from sympy import fourier_series, pi
    from sympy import *
    from sympy.abc import x
    s3 = fourier_series(x, (x, 0, 1)).truncate(10)
    p = plot(x, s3, (x, -5, 5), show=False, legend=True)
    p.show()

Now when I copy and paste the exact same code as that in the example I am getting a different result as that shown in the picture in the sympy manual. I am getting a series that does not follow at all the function f=x in 0<x<1.

Why is this?

Thanks
