Hi George,
The ‘blur’ comes (mostly) from the combination of a small Bevel Amount and a lot of Segments (for such a small Bevel), together with an Angle of 45° between the Faces of those Edges (the Edge near the top has an angle of 90°):

I hope this makes sense.
I can’t tell from just the screenshot, what exactly is causing the issue in the other image, but it looks pretty normal to me, you can get better results, but you’ll learn that later (it’s not a simple do this, or change that…).
