Logistic Regression with polynominal attributes

Hi,

Novice here. My member type is a university professor but not in the data science field.

I am trying to run logistic regression using the data downloaded from here: https://www.kaggle.com/fayomi/advertising. As stated in the data description of the site, the goal is to predict people who are more likely to click the ad. I split the data into training and scoring data.

I want to get some help in how to handle the polynominal attributes in the data set. For example, there are so many Ad Topic Line and City values. When I ran the model, it ran but the results did not look right.

Also, the confidence percentage for ad click (yes, no) was either one or zero for all rows. I feel something might be wrong here. 

Thanks for help...
