Accidentally deleted Formulas from "Balances" sheet

Help!! We have somehow managed to delete the formulas on the “Balances” tab that are under columns F,G,& H. So our assets accounts, balances, and totals are showing up but not our Liabilities.
Is there a way to recover the formulas in those columns? I don’t want to go to a previous version (July 8th) in order to recover it because then I will lose the data I’ve input since then.
Thanks for any help you can provide

I’d recommend restoring the Balances Sheet using the Tiller Labs add-on using these steps as a guide.
