Components bundled twice?

[feardarkness]

I'm using the webpack bundle analyzer and the output makes me think that some components (Screens, Bricks) are bundled twice.

As you can see in the image, seems like Screens is bundled twice? one in "concatenated" and another one outside. Is this normal or maybe I've something wrong in my configs/code?

Seems to be a problem with the styles.
