Bug: Account balance calculation error?

I have just entered many transactions in several accounts, and in 3 of my accounts in the app, the balance is not matching what my bank says. I have checked and double checked the entries, but cannot see a data entry error to account for these discrepancies. I am using version 3.2.1, and all my accounts balanced when I last updated entries 3 weeks ago. This may be hard to reproduce, but I’d like to know if other users have a similar issue.
