The image in the middle is due to the fact that the plugin is not conditioning its width, letting the user decide what width it will have. I see you have it in a space prepared for advertising, with 10 units of grid width out of 12. So you could wrap Alfie WP Weather in a div and place it inside that container, specify a width and float it to right, or, if it is a pre-designed space by a theme's options, you could add to your theme's css file this code:
As for the language files, if you added them to the plug-in they will always be erased, that's the behavior of Alfie WP Weather and every other WordPress plug-in. You could backup your .po and .mo file and then re-add them to the plug-in after updating. This won't be necessary if we had the translation to norwegian, so if yo would be so kind to send us your files, we'll be happy to include them in the plugin on the next release.
