PS 9.2: Inventory Value report shows different qty for an item when sorted by account or family

Hi,

We are at PS 9.2 PUM# 4 and are working with Inventory Value report.

Cost Accounting > Inventory & Mfg Accounting > Reports > Current Inventory Value

For an item, we are running inventory value report, we are getting different total qty when run by Account or run by Family.

I was having the understanding that Inventory value report will show the total qty that we have for an item, whether we sort by account or by family.

But looks like when we sort by family, we are getting the correct qty but when we sort by account, some qty are missing.

For your reference, I have attached screenshots of following:
