Session editor permissions for Zoom Event are different from article

I have two questions about session editors.

1.　The following article describes the session editor role.

Single session can have a session editor, but I cannot set a session editor for a multi-session event

Zoom Events roles and permissions

2.In the following article, the session editor can edit most of the session settings, though,
However, in a single session, my examination of session editing privileges shows that the session editor has only very limited privileges, such as adding shared content.

Is this a bug? Have they changed the specs?
Can someone please answer me?
