I had a look at both forms, however the form below is not made with Toolset Forms. hidden link
The form above appears to be made by the WP Forms plugin. Also the video was loading extremely slowly so i'm not able to watch it in its entirety.
If you have 2 forms made by our Toolset Forms plugin then they should produce the same results. Perhaps you may not have switched the WP Forms on the page to the Toolset one.
I changed the form today because the toolset form does not support email confirmation on registration.
However, for the sake of this discussion, I am going to revert back to the toolset form and let you see it for yourself.
The only difference between the toolset form is
1) User has to enter the First Name, Last Name, and Password but the User Name is auto-generated
2) User only has to enter First and Last Name, the User Name and Password are both auto-generated.
I did a short test on my end to see if I can replicate this issue.
I can replicate it only when i've removed the username field and the form was not set to Auto Generate the username. In this case the user's email will be used.
To resolve this you will need to edit your form in the visual builder mode and then enable the Auto Username generation See Screenshot.
Simply removing the field alone in expert mode won't generate the username without the @email.com at the end.
