Wrong titles for posts with SmartCrawl

Hello,

I've activated the SmartCrawl plugin with "Title & Meta Optimization".
I have set "%%title%% | %%sitename%%" for posts and "%%sitename%%" for home page title.

But the home page has the title of an older post. And all posts have the same title of an other post.

What am I doing wrong here?

Thanks,
Martin
