The user profile page doesn't display Username & Password fields correctly

Hi!

I'm creating a custom user profile using MB User Profile and Custom Fields, then adding the CF to the page id="perfil-del-cliente" label_submit="Actualizar datos" confirmation="Tus datos fueron actualizados"]

This works to show the custom fields for logged-in users, but when I see the page logged out
the boxes are very small: https://prnt.sc/1qp3n1a

If I see the page on a smaller screen the boxes work: https://prnt.sc/1qp3pqf

I tried disabling all the plugins except MB and MB AIO, and the problem remains, so it doesn't seem to be a compatibility issue with other plugins, I also changed the theme and the problem remained: https://prnt.sc/1qp3wdt

This all points out as a Meta Box issue.

Any ideas on how to fix this?

Thanks!
