problem importing posts from blogger

Hi. I’m trying to use the Import feature with a new WP blog, and pull over my posts from my older Blogger blog. I go through the steps fine, have Google grant WP authorization, select the “magic button” to Import my posts, and the “import” button quickly turns to “set authors”, and I’m brought to a page on which, supposedly, I am to select the WP login from a dropdown list to associate with the “Blogger username”. But there is no Blogger username displayed. (And hitting “Save changes” just brings me to my WP Edit Posts page.)

What am I missing?

Thanks,

Seth
