differences bt BL budget & act. for past periods when converting and assigning current project as ba

 Dear Experts,

Kindly check below Issue and let me know your idea/solution about that: 

Problem description: 

1-  I converted the current project as baseline and assign it to the project.

2- in the administration Earned value setting I choose either of one of the options "Planned Value with current date" or " At completion values with current dates" 

3- I expect that the baseline schedule bars to be same as the current schedules bars which is correct no problem on that. 

4- I also expect that past period actual and BL Budget be the same (before data date) and the balance budgeted values (or units) to transfer to remaining period of each activities
