cash at bank and historical balancing problem

Hello, I urgently need help and I am super confused in regards to my cash at bank and historical balancing. I started off with a opening balance for cash at bank with $10,748 and current balance of $10,426 and had a 0 historical balancing. I had an issue with the remaining balance and wanted to make it 0. Next thing i know, my cash at bank would always be opening with $10,426, and either closing with $10,386 with 0 historical balancing, or $10,426 with $40 historical balancing. Pls help
