How do you delete a text box when using an iPad

I can create a text box when working with kami on an iPad, but the delete button does not seem to work. Is there a trick to getting the delete button to work or another way to delete beside the trash can button? I know I can delete just the text out of the box, but I want the entire box gone. I also can not edit the font size or color once the text box is created using the iPad, so I would also like to know how to do that. Thanks!
