Bug: Negative Journals do not add "against" value to GL Entry

I have noticed that when a negative Journal Entry is posted, the General Ledger entries created from this do not have an against value:

Any journals created via the same method that are positive do have the against value. I’m not sure what could be causing this, nothing in the code jumps out at me.

It is possible that this is an issue, if you are on the latest master branch, you can add replication steps on GitHub and raise an issue.

But I am not sure if its valid as per Accounting Practices.
