registered email addresses not there

[Ivette1]

Dear community, I have created two meetings in tow different weeks for which you have to register.
In the first meeting, all registered email addresses are displayed in the queue report.
In the second meeting, no email address is entered, although a bunch of people were in the meeting and they all had to register to get the zoom link. I am at a loss. The queue report is empty.... Thank you for your help.
