PDF Architect - Whiteout height

I just upgraded to PDF Architect 8, and I'm trying to use Whiteout or somehow cut out some existing embedded text in a PDF document. When I use the Whiteout tool, left click/drag whites out everything from top to bottom of the page. Is there a way to adjust the height of the tool, or is it just buggy?
EDIT: I just tried the "Create Redaction" function, and it does the same thing - Redaction is from the top to bottom of page.
