Current view which changed automatically within SAP BPC Web interface

Dear Sap Expert,

We have SAP BPC 7.5 NW SP10

We faced with the next issue :

When we work in web interface, we have in current view  application set equal to "SAMRUK_KAZYNA", however, when we choose several operation (as BPF, monitor or any other) we found that our current view changed automatically and application set now is equal to "FNB_SK_MR".

This problem actually very critical because we have different BPF on different application sets (Screens are attached).

Could you please explain how to solve this problem.

Thanks,
Kadraliev Erlan
