In the chart of account , if i select bank i only get to see the general balance at the top , i would like to see the balances per transaction

A possible reason why you can't see the balance column is because your browser is zoomed in. Zoom it out to see the results and view the balances per transaction.

I'll attach some screenshots for visual references:
