Personal projects display

Hi

My gitlab server is :

GitLab 10.5.1
GitLab Shell 6.0.3
GitLab Workhorse v3.6.0
GitLab API v4
Ruby 2.3.6p384
Rails 4.2.10
postgresql 9.6.5

If a user whose name is kindman , and he has created quite a lot of personal projects.

Why “http://mygitlab.com/admin/users/kindman/projects” only show some personal projects,
But
http://mygitlab.com/users/kindman/projects” show all ?

Thank you for your reply.
