Double output

When I run the following:
`program example`
`    x=1+1`
`    print *, 'Hello, World!', x`
`end program example`
I get the following output:
/usr/bin/ld: warning: libgfortran.so.4, needed by /home/nuker/anaconda3/lib/libmpi.so, may conflict with libgfortran.so.5
 Hello, World!   2.00000000    
 Hello, World!   2.00000000    

Is there a reason I'm getting double output?
