Depreciation is not sync with inservice date

Hello all,

few assets are depreciating before inservice date....

here is example:

picked one asset with inservice date 2011-01-01. ran depreciation for this asset. depreciation is starting from 2011 after inservice date which is good.

Now, I changed inservice date to 2013-01-01 for this asset . ran depreciation for this asset again.  for some reason, depreciation is starting from 2011 instead for 2013

i dont know what dates are effecting. Any help will be appreciated
