When we complete a path, it's automatically recorded as being completed on that day. In some instances, the path was actually completed at some time in the past (anywhere from a couple of days to 3 months ago), but is not being updated in NationBuilder until now. Because we are reporting on our paths based on the completion date, it would be really helpful if we had the option to change the path completion date.
Thank you for reporting this issue and why it's important to your use of the product. We do not have a timeline for this yet, but will keep you informed as that changes.
