No "Three Dots" for Editing User Email Addresses

Good afternoon, all.

I have seen variations of this question on the support threads, but never a conclusive answer and instead a fair amount of deflection to other threads which proved dead-ends. Bottom line, I am the administrator for a Team/Pro account with six users, including myself. We recently moved to new email domains, which I am trying to update in the Admin Console. But I can't.

The online guides claim you can edit profiles - including names, etc. - by navigating to Admin Console/Users and selecting the person in question. That is not true. When I try, I get this ...

There are no three dots. Not there. Not where they're supposed to be. And when I do examine the available options, the closest solution I can find is to wander through the business of downloading/uploading in CSV format.

If I am forced to mess with CSV, then I guess I will. And I guess I'll cross my fingers and trust that that will work as advertised. But it won't explain why the editing interface doesn't appear as Adobe claims... and the back-and-forth with CSV manipulation is a lot of extra work, too. Can someone explain what is going on?
