The Verbum source criticism filter applies to all Bibles which should include the NRSV. Yes, it has and I own a RVI. In this particular case, the filter was on when I opened the book, I turned it off then when I went to turn it back on it was gone.
Thanks for the report. I think this is another instance of a problem that multiple people are reporting with visual filters vanishing from the Visual Filter list. I've added a link to this thread in the case for this bug.
