Optional Prompt displays prompt in report view only

[patrickthatcher]

I have a prompt page that contains an optional prompt that works as expected when running the report directly. However, if we create a report view on the report and do not set this optional prompt, the default prompt page is display for the optional prompt. If we click the OK button without selecting anything, the report does render as expected.
How can I figure out that is causing the prompt to display?

Thank you

A little more information I discovered:  The optional prompt only displays when setting the prompt values from Properties -> Report View -> prompt values

Figured out the issue.  We have multiple report sheets within this report and are also utilizing cascading prompts that are being rendered depending on what previous prompts are selected.  By changing the prompts blocks from Render Variable to Style Variable and setting the box type = None, the unused prompts are not removed but instead hidden.  This keeps the parameters available to be checked.
