Not sure but perhaps its best to wait til you have successfully disputed them. Good luck
It's best to wait, since from NFCU's point of view there's the chance you'll "lose" the dispute so until it's settled the item will still be looked at as belonging to you even with the dispute notation.
Also, you won't have the advantage of a corrected FICO score until the dispute is resolved (assuming it's resolved in your favor, of course.) 
These days disputes are generally taken care of quickly... if it's cut-and-dry you might even have results within a week. If the item is "verified" as belonging to you it will of course take a bit longer to get corrected, but in any case the turnaround time is much better than it once was.
Hang in there!
