NEED HELP WITH WEB SCRAPER GOOGLE CHROME ADD-ON FROM WEBSCRAPER.IO

I have questions about how to use it that I might ask at any time. Time zone is East Coast US (New York City.) I am just learning now. There is no real budget. A price per question? Per minute of on-line chat? Per page of answer?

Here is my 1st problem. The data is missing even though it displayed for the first item in Data Preview. Can you explain why/how to fix it and if so how much?
