Can't Find the variables in the Text Aggregator

Hi Team,

I used Get Rows and added column names. Then created a Text Aggregator but i can;t see the columns created in the Get Rows, can anyone help me on this. 

I need my column name like  “ 4.Invoice ID “ but i got only the Total number of bundles and Bundle Order Position. 

I tried publishing, ran only get row, re-loaded, even logout and retired.
