It was good to be able to access my site.
I saw the image of the test site you specified.
But it is not the essence of the problem yet.
Because the pull-down menu of that tab is not outside the article posting area.
Please see the image attached to my first post and compare with both.
That is, the function of 'content ordering' etc. under the tag function is hidden.
This customization is attached to the article of Sep. 11 1:43 am.of my mail.
I appreciate your efforts.
Thank you.
