$0 line in Mass Additions Posting Report

Hi,

We use projects at our site. When the data comes from projects into fa_mass_additions table, I observed that two lines are created one with MP and one with MC status. ( there is one MC line per each source line ) OR rather one MP line is created for multiple MC lines

1) on running post mass additions , a single asset is created , the posting report output shows two lines for the same asset , one with a $0 cost and one with the actual cost of the MC line

2) similarly on the source lines window two lines are  created

3) When I drilldown on the $0 line, it goes to " some" other source line - since it is the MP record
