show only chosen month for two different date fields. But the month field is created from one of the date fields

[arunqlik2view]

Hello All, 

I have 2 dates fields  "Date" and " TransactionDate". Now, I have a month field created for "date" column. So when I choose month from the listbox it forces to show all the rows for that particular month , which is normal but it also shows the previous month's value in the "Transaction Date" just because the "date" is still current month selection.
I'm sorry if this is sound confusing. Please do  check the below image for more detail, it will easy for you understand once you have a look  . 

Please tell how this can be achieved I  have attached the sample qlikview file for you to work it out.
