Unable to add widgets to upfront

Hi,

I am having issues when I try to add a widget in upfront, when I add the widget and go to widget setting (please select widget in settings) none of the widgets seems to work, for example, if I select a text widget the field to write the text is not presented, then if I save the widget and reload the site, it doesn't load, I get a blank page, I am currently using a theme built with upfront builder, I also tried the same using parrot, but the same thing happens, any help would be greatly appreciated.

Regards,
