MTD values in cube view

Hi all,

my client is loading in OS Actual data in MTD.

I set up a cube view to show the actuals MTD month by month. If the user loads the first 3 months, the cv correctly shows the MTD for the first 3 months, but for the 4th month it shows the YTD with inverted sign:

If I understand correctly, this setup should be configurable by intervening on the following WF Profile settings:

I also changed the following setting in the scenario configuration:

nevertheless, the cv keeps showing the inverted YTD in the new month.

Can anyone explain why?

Thank you!
