White mark before comment

Hi,

Firstly great plugin, found it much easier to configure than rival review plugins.

I’m having an issue with the plugin when it displays the comments left. For some reason its leaving a white line before the comments.

I can’t figure how to get rid of this.

Any help would be appreciated.

Thanks
