How out of balance shows in cost summary or detailed reports?

Summary

One intangible asset and another asset adjusted from invoice is showing out of balance in report

Content

I created an intangible asset with no depreciation with $500,000 value in Jul month. 

Another asset was added from AP invoice. The AP invoice Asset was added in June month with $140 cost and adjusted in July month with -$50 cost. Thus current NBV is $87.5 ($2.5 went to depreciation reserve after depreciation was run in July). I don't see any Depreciation line for Jun and July month. I ran depreciation as well as Create accounting for the Jul month.

These both Assets are shown as Out of Balance in Cost Detail report. There is 0 beginning and ending balance for these lines. What is the reason for that?
