I tried using incognito window, but it turns out the issue wasnt my cache as I had the exact same issue.

I then fixed the issue by reactivating the credit2 and chequing2 accounts, then manually delete all the transactions then again void those two accounts. As long as the transactions are 0 in those accounts, when you void them, they wont add to expenses. I think this is a bug, as you would think that when you void an account, you dont want any of its data interfering with your regular accounts.
