Does anybody tell me the rules of videos listing?

As for my latest video case "[MMD] Amaha Sora dancing Idol and AI" https://deovr.com/zl2dyx (with the tag "dance") which I posted on Dec. 5,

It appears with the "dance" tag on the new list
https://deovr.com/categories/dance-vr?sort=new
But it is NOT on the new list
https://deovr.com/videos?sort=new

Sometimes even worse. At the case of "[MMD] Dog girls in rabbit costume at Rithym" of Nov. 24 at
https://deovr.com/d2mmrj (with the "dance" tag), it never comes on:
https://deovr.com/videos?sort=new
https://deovr.com/categories/dance-vr?sort=new
It is visible only on my channel :
https://deovr.com/channel/tubep

Similarly, some of my videos are not listed. For examples:
Nov 29 https://deovr.com/8ss3lf ... OK
Nov 25 https://deovr.com/xca82n ... not listed
Nov 25 https://deovr.com/zhwnp9 ... OK
Nov 24 https://deovr.com/d2mmrj ... not listed
Nov 12 https://deovr.com/p17ean ... OK
If you visit https://deovr.com/channel/tubep , you can find the videos of lower views cannot be found on videos list while the others can be.

Did I do something wrong on uploading my videos?
(I wonder DEO reviewers secretly force some of my videos to be "unlisted" visibility ???)
