Data issue on Ad-hoc report--Urgent

[#1]

Hi,

I have one m_time_bckt table in database which has the data for both currnt and previous

In each year there are 4 quarters. and each quarter contains 3 months like

Q1-->Jan, Feb,March etc.

Issue is the April previous month is March.So when I am selkecting Quarter 1. Its showing all the 4 months in it, but basically it should display only 3 months,I have attached the screen shot for the same.

Can I restrict it on report level.

Thanks in Advance...!!!
