Looks like it's taking it from the "title" of your Blogspot link.
If you click on the Blogspot link in the WYSIWYG editor, then click on the link icon, you'll see the URL in the Title box.
Once you change/remove it from there, then within a short while it should disappear from your Broken Links report.

Hover your mouse over the Blogspot link and the popup "tooltip" has the wrong link in it. That's because the wrong link is in the "title" attribute of the link.
The instructions I gave previously will let you edit (or remove) the title for the link.
