Incorrect hangling page name with hyphen "-"

Hmmm … that is curious, because CMW doesn’t really care about urls and it doesn’t do any filtering by menu item titles. At the front end, the only time it looks at a title is if you set a Title From option, and even then it simply takes it and outputs it (suitably filtered, as all titles are).
In admin it displays menu item titles in the “assist” and the children-of SELECT, but it only uses/stores ids.

Could you expand a bit on “it doesn’t work”, please?
Like … Is the problem with admin, or at the front end? Is something being displayed, or nothing? Is there a partial or scrambled display? What settings are you using? (maybe you could show me the shortcode equivalent?) Are you using it as a shortcode, as as a widget? If you have options set, have you tried simply leaving it at Show All (with no other options modified)?
