Several issues with Custom Page Box. (That is: Settings > Customization ... Side Panel > Add element > Custom Page Box.)

1. Having created a Custom Page Box in the wiki, how do I re-use it in a workspace?

2. Having created a Custom Page Box, it then appears in the Navigation. How do I stop that from happening?  Hmmm, this appears to be the same as this problem from 6 years ago:  https://help.zoho.com/portal/en/community/topic/how-to-hide-this-custom-navigation-thing%3f

3. Worse yet, somehow things got into a state where every time I click the Save button on the Customization page, it saved an additional copy of the Custom Page. So if I click the Save button five times, having done no editing whatsoever on the customization page (including not changing the Custom Page), then five copies of the Custom Page got saved and clog up the navigation display.

In the mywiki.do display, these appeared with increasing number suffixes. This definitely seems like a bug. However, after deleting all the Custom Box files, I was not able to reproduce this problem.
