OM System 20mm 1.4 focus issue

I have just receive my copy of the new 20 mm lens. I have been testing full-open (f1.4) since this is why I want this lens.

I was looking at results and it seems quite soft.  I then realized that there is an auto-focus issue: I obtain sharper image when I focus manually !

Anyone has an idea of what happens here?  I have never seen similar issue on my other Olympus lenses. Any suggestion how to resolve it ? (apart from return the lens...)

Thanks !

BTW, I like the rendering in general. Just poor when magnify at 100%.
