Zero App submission form text area field doesn't keep text editor styling

Hi,
I've used Zero App to build animal profil files for an animal shelter with custom fields. Everything works fine except for the text area field. I've activated the text editor for that field but every time you submit the form, all the stylings (paragraphs, bold, italic, etc.) disappears and I end up with a brut text bloc.

What is the use of the text editor if it doesn't publish the text styling? Is there a setting I'm missing or is it a bug?

Thanks in advance for the help.

Best regards,
Denis.
