Settings On Page

Hello,

Thank you for contacting Rank Math today.

Rank Math makes use of some custom fields to save general settings for each post on the post meta table. Some of the settings(like the ones you have highighted) will be saved with default values if they are not being used for your post.
You do not need to worry about this, I can also suggest that you disable the WordPress custom fields meta box to increase page load speed if you do not use it when editing posts. You can do this from the “Screen Options” menu at the top of the page:

I hope this info helps. Thank you.
