Hi.
I was training on the KQL queries and I noticed an error.

Write multi-table queries by using Kusto Query Language
Unit 5 of 9 :Exercise - Combine table results by using the lookup operator

On this page, demonstrating the usage and better performance of lookup on table,

-->the query below should return the same results as the join kind=leftouter from the page

I don't know if I missed something, but I don't have the same results, and the screenshot of both pages are also showing different results :D

Join leftouter results :User's image

Only the first row is identical.

Regards.
