APO DP - Key Figure Type A - Average of key figures

We are having issue with downward dis-aggregation of key figures of this type.

If you enter a value on a high level, the system is supposed to disaggregates it by copying the same value to the details on the lowest level. However we get into situations where the value is copied only on few levels. The only painful solution we have found so far is set it to zero then save and repopulate it and that is very time consuming.

Is there way to stop/fix this type of behavior.
