Can you experts share your knowledge and confirm it the system behaves as expected or if there is some bug/missing settings?

Below is the description of what we found out:

The System is adding additional forecast just beyond Planning time fence, where it’s not needed, since the forecast within the Planning time fence already exists and covers weekly needs.

The Total forecast for May in MS1 is stated as 40,5124 according to the Demand Planner

Importing Demand Planning forecast:

The system is adding additional demand on the 8th of May which is not correct, since there is already a forecast for the 6th of May, that covers the entire week.
