Reply To: Add Numbered List to Running header

I just responded via email, but I’ll respond here as well.

It’s likely a bug using the combination of “all instances” and “only numbering”.

One work-around which would likely work, would be to use a GREP processor to strip out all non-numbers.

Some more details that I did not write in the email:

Something like [^\d.] (and replace with nothing) would delete anything but digits and periods. That might require cleaning up trailing periods and if you have numbers in your text, that would be a problem.

A better GREP might be:
.{0,}?(\d\.\d)[^\d]+ and replace with $1

I think this would do it. If you have some kind of separator, you would need to add that in.
