I think deleting your personal transactions is likely to be the better way. Although it would mean your balance is going to be different from your actual bank statement, it does mean that none of your personal transactions show up on your balance sheet (9998 Suspense Account also shows up there).
You could alternatively tag them to your drawings account, so they wouldn’t be sat in the suspense account.
Long term however, I recommend looking at a dedicated business account, just to help things neater and make life a bit easier with bookkeeping too.
Hope that helps!
