Unknown entries when templateMetrics is run

When I run templateMetrics, I have got a few unknown entries such as __dd3ba228413ddbd68d1b351a698d6167, __fbea797df4cdee28d369386c47f371ba and so on. My updated version is slower than my older version. Can the unknown entries be a reason to it?

I would also like to know how is the other pages created count calculated?

I’ve never seen anything like that. Do you have your site’s code online where we can clone it and see for ourselves?
