Error with Core Results WP

Hi,

I am working with the Core Results web part for a custom solution,
modifying the XSL template to change the look of the search results
page. I have been moving the search fields around and formatting, and
all is good.

However, I want to add a couple of fields to the search results. I
have a field under "Managed Properties" in Central Administration
called "LastReviewedDate". This is populated from
"ows_Last_x0020_Reviewed_x0020_Date". I did a Full Crawl, everything
looked good. But, if I configure the Core Results web part and try to
add "LastReviewedDate" (or "ows_Last_x0020_Reviewed_x0020_Date" for
that matter) as a new search column, I get the error "Property doesn't
exist or is used in a manner inconsistent with schema settings." when I
display the search results.

Am I missing a step that I need, to add new fields to the search
results using Core Results?
