I missed a line in my report and I do in fact create a 1:1 class
before attaching to it. I have found that if I change the prio value on the
filter lines to unique numbers that I no longer get the error. I am however
confused as to the meaning of the prio parameter, and I'm not sure why
these filter lines need unique values or exactly what impact these values have.
