Primavera P6 Professional API 8.3.1 Issue

We are on Primavera P6 Professional R8.3.3 using the Primavera P6 Professional API R8.3.1.

Through my program I am setting the "Link actual to date and actual this period units and costs" to true programmatically (i.e. project.setLinkActualToActualThisPeriod(true)).

This Checkbox is located on the Project Details (Calculations Tab, Resource Assignments Section)  Through the front end with the checkbox on you can update a Resource Assignment Total Actual Cost and it will automatically calculate the appropriate This Period Actual Cost.  It uses the Previous Financial Period Values to come up with This Period Actual Cost.

Unfortunately when I try to set this checkbox via the API it is not calculating the This Period Actual Cost correctly.  I put in an SR and they were not able to replicate the problem.  Our projects have Financial Periods going way back and sometimes there are over 50 Previous Financial Periods.  I believe the API has some sort of limit or something on the number of Previous Periods it is picking up.
