Void JE didn't void the AE portion

A user entered a goofy JE that crossed companies when it shouldn't have. He entered reversing lines on the same JE to back out the bad portion. Something looked odd about the JE so he asked me to look into it. (His entries are posted.)

I inquired on his JE in production, and copied it and pasted it into our test system and posted it. It created an AE entry. Great. Just like in production.

Then I inquired on my batch again. From Batch review, I clicked Void JE from the exit bar. It reversed the JE just fine.... but did not create a reversing AE.
