Power Bi does not detect newly added columns to connected csv

Hi, 

I built a dashboard with a csv. Now i oppened the same CSV and pasted the new data (retained the existing header) along with new columns. Total rows = 201,032. I have spent lot of time and money on this dash (hiered a freealncer to do some DAX). How do i get PBI to pick up the new columns. 

NOTE: The data is being picked up when i do refersh just not the new column values. Please help
