I've tweaked my Apache configuration but don't seem to be able to trigger a rescan--the cipher list doesn't appear to change. I guess it's cached for a little while, but the UI doesn't make that clear.
Also, it's flagging the following ciphers:
ECDHE-RSA-DES-CBC3-SHA
EDH-RSA-DES-CBC3-SHA
DES-CBC3-SHA
These are triple-DES though, rather than just single DES. Is that considered weak these days?
