The result is wrong when using multiple dimension with in filter which including multiple filter value

I have a cube with 17 dimensions, when I query from the cube using multiple dimension with in filter which including multiple filter value, the result is not correct. 

But if i query the cube first, then filter outside the result in another query, the result is correct.

Or if i add trim on the dimension when query the cube directly, the result is correct too.

Till now, I do not find other cube have this question. I do not know why?

I attach the snapshot of the query and result.

Thank you!
