Pages With Featured Snippet No Longer on Top of Page 2, Gone from Top 100

A few days ago Google decided to not show pages that has won a Featured Snippet in the SERP on the first page, those results were position 0 (Featured Snippet) and 11 (position 1 on Page 2), it looks like that was a bug and Goole has nuked them from the top 100. The entire point of deduplication is to not repeat a specific URL that’s already been displayed at the very top of the results, so this kinda makes sense but if you monitor your ranking be warned position 0 is likely not counted by most rank tracking tools as an organic position you most likely you will see those keywords as not ranking in top 100.
