Skrooge credit card reconciliation

I am transferring from Quicken to Skrooge.
I tried importing using QIF format but am missing my credit card transactions (operations). I have 2 issues, if someone can explain.

  1. My bank QFX download has a different account number. I changed the account number but the import puts them in a new account. Not a big issue, I can just move them, but would like to know why.
  2. I entered my account balance and imported the transactions, which all match up. The problem is my Delta is not accurate so I cannot reconcile without entering a fake operation, which now gives me a wrong balance. How can I correct that?
