Kee doesn't "see" Crashplan Pro fields

I’m having trouble getting Kee to “see” the username and password fields for

I’ve gone into the Kee tab in KeePass and verified that the username and password form fields match the html id of the fields on the page. URL match is set loosely to partial Domain match. The add-on works fine for the other 50 or so sites I have set up, but this one has me stumped.

Any suggestions?
