Depreciation expense and accummulated depreciation Jan-May 2016

Good day all,

In my efforts to reconcile Fixed asset accounting in Oracle , i noticed differences between depreciation expenses figures and accumulated depreciation(see attached files-Jan to May). Depreciation expense and the attendant accumulated depreciation account should be same in the months. Please i need more clarification as regards this . Thank you
