Multi Period Accounting Issue - Creating unwanted deferred Journal Entries

Hi,

Multi Period Accounting is creating the unwanted deferred journal entries.

Below is the scenario:

AP Invoice was entered. Invoice total amount = 2,486.70

There is only one AP Invoice line of 2,486.70. At AP line level; Deferred check box is enabled & Deferred Start Date - Deferred End Date entered as 01-JAN-2016 to 31-JAN-2016

After performing invoice validation - create accounting, this AP Line has got amortized for 12 months instead of one month.

The deferred amortized journal entries were created for 12 months. Like - 01-JAN-2016 = 207.23 / 01-FEB-2016 = 207.23 / 01-MAR-2016 = 207.23 / & so on till DEC-16.-----(This is incorrect/not required)

There is no need to create an amortization for 12 months.
