Why does Instant Data Scraper stop scraping website URLs and delete the column of the URLs it has already scraped? Is there a way to fix this flaw?

This is a limitation with Instant Data Scraper. When you are scraping website URLs, it may just stop gathering URLs and also delete scraped ones. The way to fix the flaw? You cannot do much about it. You can tweak the settings but not sure if it will solve the problem. You will need to look for alternative tools.
