Filters using hierarchy nodes showing additional values

Hi,

We have built a query which uses structures. One of the structure element is defined so as it fliters the data by restricting the characteristic values for segment. For example, if there is hierarchy for 0Segment as below:

Root

Node 1

Subnode1

Subnode2

Node 2

Subnode3

Subnode4

Subnode5

Subnode6

and we selected the filter values for 0Segment in the structure element as it should display Node 1 and all its leaf's and also should display Subnode4 and its leaf's.

But when we execute the query Subnode3 is also getting displayed in the result which is wrong. Can anyone let me know what would be possible problem and its solution.

Thanks in advance.

Regards,
