Thanks for your quick response. I was also thinking that it wouldn't matter but I thought it would be worth correcting if possible. They are known to get hung up on this type of thing for sure!
Your example is clear and to the point and I was thinking about doing something like this but I wasn't sure how to word it.
I do believe that they will ignore it but it's worth putting in the record anyway. Fortunately, my DBQ and Nexus letter did not have a specific date and I have no additional supporting statements referring to that date.
Thanks again for your time.
