Changes to the AP Distribution for project related information not reflecting in the AP Invoice line

Hi,

I have created a project related AP Invoice for a non matched PO and created the line with project related informations like Project/Task/Expenditure Type/Expenditure Organization & Expenditure Item Date. The same information got populated in AP Distributions level. However, when I make changes in the AP distribution level for projects (like changing the Task or Expenditure Type or Exp Org) before validating the invoice, the same information does not get automatically updated in the AP Invoice line level or vice versa. Is it an intended functionality where we need to manually go and make changes to the line level or
