Bank feed incorrect

Hi

My Monzo business account feed is showing the wrong current total and there are a few transactions missing too. I've also noticed wrong transactions, for instance money I have moved into the tax pot is showing as the wrong amount or placed into a different pot. I think you will tell me to remove the feed and redo it but would that mean reconciling every transaction again? I really want to avoid doing this as it took hours to do the first time! Also I have submitted my Q1 and Q2 to HMRC so if the figures on there are wrong, do I need to resubmit or would that just be done when I do the full return next year?
