Consolidation works for January, but gets false data for February

Hi there,

I have a strange problem when consolidating our initial Closing Balance. Perhaps somebody can help me? Here's the situation:

We are loading the initial closing balance per file integration for Dec-22 with
Data Source: FCCS_Data Input
View: FCCS_Periodic
Movement: Custom Member (under Parent FCCS_Mvmts_Subtotal)
The Consolidation to Jan-23 works fine, the numbers are correctly carried over.
We then load the transactional data for Jan-23 with
Data Source: FCCS_Managed Data
View: FCCS_Periodic
Movement: Custom Member (under Parent FCCS_Mvmts_Operating), everything looks exactly how it should look.
We then consolidate again for Jan-23 and then for Feb-23 where the problems start.
