Question...I installed the nano wallet on my mac, but when I imported my old wallet, it didn't reflect every transaction made, so the nanowallet has significantly less xem in it. I still have the old one, but I'm hesitant to do anything for fear of losing all of my xem. What steps do I take to start over the process of installing the nanowallet and importing the old wallet to show the correct amount of xem? Or is there a way to correct it without having to re-install? Thanks.
