AK902 Question

I have an old version of EdiFabric before 9.6.4 and I wanted to know what bug the changelog was referring to here.

"Fixed a bug for X12 999 & 997 acknowledgments generation in AK9"

I am seeing this get generated "AK9*A*1*10*10" in response to an 837 with 10 ST segments inside a single GS segment. I would expect AK902 to be "10" but instead its "1". Was that the bug that was fixed in 9.6.4?
