Dear Peter Blaha and wien2k users,
                    I need to know that is my problem related to bug or
something else. I have to mention it here that I have another similar
structure with same space group  P21/n but only change in A site cation.
But in that case I did not get such problem and it worked properly. Then
why in this structure I am getting such problem. If you could tell me I
could solve it anyway. Thanks.
