Why is my P&L Report showing a full year's Depreciation costs?

This is expected behavior. All monthly Asset depreciation amounts are calculated in advance for the life of the asset. 

So, if you select the current Financial Year (Reset to Current FY button) for your P&L reporting dates it will report the whole year's depreciation (and all other future-dated income & expenditure).  If you just want the year to date numbers select the Year to Date button instead.
