Kmail filters - looks to be a bug?

I use kmails filters to sort incoming emails. All are working except for one and that’s the one that sorts on the basis of from being in my address book.

Curious thing is that when I start typing an address that is in my address book it auto completes correctly so that aspect seems ok. Also suggest that my address book import worked as well.

However if I use tools - address book I see 2 marked “default address book” and “address book”. Both contain the same thing.

(Just noticed that if I click on each of these it looses the right hand pane’s content for both.)

Any ideas ?
