I have re-set the paragraph rule, but there seems to be a glitch where it has retained the orig rule underneath, thus making a double line.
Doesn't seem to be any way to remove. Double checked settings and it is on 'solid'.
In the paragraph rule dialog, there is a drop-down menu to choose rule above or rule below. My guess is that one of those was applied, and you adjusted the other, so now you have both.
