Different results in monthly / yearly planning reports

Hello,

Using v10.2.3, I notice we can get different results from two Planning reports which should give the same result.
I think the issue occurs only for months having both real and planned work.

Example for the current month (April) :
- monthly planning resource/project :
   - total for resource "YP" = 19 d
   - total on project = 706.06 d

- yearly planning resource/project (only looking at the month of April) :
   - total for resource "YP" = 38.8 d
   - total on project = 1124.77 d
