I have had a similar situation recently. I wasn't paying attention to my filing and then I filed one of my nails down way too far. I personally am still growing my nails out so I just keep them at the uneven lengths since the long ones are still not where I want them to be. You could also try to get some sort of a growth serum to help the shorter nail grow faster to catch up with the rest of your nails. HTH!
