Issues with fixed assets depreciation

I entered the fixed assets with value in 2016. I entered manually the depreciation entries for the year 2016,2017,2018.
Now i created the report Depreciation calculation worksheet for the period 1 Jan 2019 31 Dec 2019

as depreciation value for the 2019 the system calculates the depreciation based on the residual value on 1 jan 2019 and not the original value .
what did I do wrong?

You failed to read and follow the Guide: The worksheet uses the declining balance method for depreciation. You apparently expect straight line.
