The balances didn't go anywhere because they are still located in your bank account register, @sgobeauty. Rest assured that I've got the steps to resolve this.
When going to the account register for the first time, the default view in the Balance column is set to n/a. That's why the balances aren't showing in this column.
There's a button that we'll need to select so your balances will appear again. Just click the Date drop-down under the Filter icon. I've attached two screenshots below to compare the results before and after clicking the Date option.
While working in your account register, you can add transactions directly to it. From there, you can also find, edit, and review them. For more details, visit this article: Managing Transactions in Account Registers.
I'm just a comment away if you need anything else. Enjoy the rest of your day, @sgobeauty.
