Hi,
We were kind of embarrassed by that one. We thought we had QA'd it pretty good, but clearly we didn't. Thanks for reporting it.

We are working on a fix. But also we are working on several enhancements to make the chord finder more like the scale finder (printable chords is the major difference). I don't have an ETA for when we can deliver it to you, software due dates are notoriously unreliable. But...if it isn't done in a couple of weeks, we will fix the existing chord finder instead of waiting any longer for the new one.

Jon
