Wadauthor problem

First, I change a linedefs property to Water block translucent. Then I click OK. I go back to the same linedefs property, and it stays the way it was before I changed it.

Sometimes, WadAuthor sucks like that. I've never had the problem with anything more then some Map Things, though, and I have no clue what causes it.
