when making adjustments to your description, if you try to change the alpha of the backdrop to 0 it won't make it go invisible

go to customize text backdrop > background > flat or faded > select any color for testing > set the alpha value to 0 when it gives you the prompt and observe how it does not make the backdrop invisible
 
(for the record setting it to 1 is technically a workaround but probably not how it's expected to work)
