SEO Soft Errors

I am continuing to get a whole lot of “soft errors” when I do an SEO scan for the following:
4xx Soft Error

There’s a few things wrong here, but for some reason it is choking on this link:, which appears on all of our calendar events – which are supposed to be excluded from the site map anyway, so I’m not even sure why they are included in these scans/reports. Also, most of the time the ‘IGNORE’ button doesn’t do anything, so I can’t even get rid of them. Any guidance appreciated.
