Blight is a strong word, but it definitely doesn't fit. The background is a different colour, it only has a border at the top (and it's differently coloured compared to the other borders), and it's a sharpened rectangle when all its neighbours have rounded corners. It does stand out a touch.
Thanks. Agreed on the design that it needs improvement. Could you please elaborate little more. Might be able to fix few.
