Asset and Depreciation

Dear All,
Trying to add an asset (2000 cost) which was bought on 01-06-2010 and the number of Depreciations is 6 with Frequency of 12 …
With this I thought that the calculations would be:
01-06-2011 - 412.50
01-06-2012 - 412.50
01-06-2013 - 412.50
01-06-2014 - 412.50
01-06-2015 - 412.50
01-06-2016 - 412.50

But instead it does not allow me create this way … only accepts if Next Depreciation Date is equal or after the current date 23-06-2016.

Any help to understand if I am the one wrong or the system was made for items on the current year?
