Troubleshooting Email Issues and Data Discrepancies in Lesson 2

Hi there, On Lesson 2 i used the waterfall for emails and because there are various providers they ask for different inputs. I noticed that two emails end in @linkedin.com although the prospect doesn't work there. How can i fix this? I saw this before and was told the provider used the Linkedin URL not the company domain to search for the email. But looking at the provider, it is being directed to use the company domain. Also, the table only has 10 names, not 50 like the lesson suggests. Am i missing that too? Please can you help me with these two questions. Table.
