"Thanks for the report, Anne (and thanks for escalating, Stevie!). This looks like an issue with how the data is displayed in Webmaster Tools, it shouldn't affect your site's crawling, indexing or ranking. I don't have any specifics at the moment, but the team is looking into the details to see what we can do here. Thanks for your patience & sorry for the confusion!"
