I created a new long term liability and applied a balance in the opening balances. Then realised the account was not going to work as needed and I needed an 'other liability'.

So I removed the opening balance and saved changes, so I could 'delete' the account, however I am still unable to delete the account, and the view transactions is still showing up a transaction of Credit "$0".

This may be why it will not give me the delete option?

I did not enter '0' in the opening balance, I just cleared the field and let the system reset the figures.
