Problems with multiple accounts showing wrong amounts after updating

I recently updated to 21.16. After update multiple accounts had wrong amounts -- a car loan with a balance of $20,000 now shows paid off in April of 2017! Bank account has a balance of $9,000 less than it should be. I found update 21.17 and updated to that with no improvement. Is there a plan to push out a patch or fix for this? Thanks!
