Expert Response
We don't know what's damaging the columbines. We agree that the symptoms do not suggest leaf miners or powdery mildew. It might require an expert's help or even laboratory analysis to determine what's causing the problem.
The following publication indicates, without providing much detail, that columbine is susceptible to a number of perhaps somewhat uncommon leaf diseases,

If the problem persists, consider sending samples of the affected leaves and stems to the University of Minnesota Plant Disease Clinic.
