I've updated a plugin now I've got two versions appearing in my plugins menu?
This means the plugin that you updated has a non standard method of installation, generally this happens when the install process tells you to just upload the php file of the plugin to you plugins directory, rather than the whole folder. If you look in your plugins directory you will have a newly created folder containing the updated plugin. Open the readme and see how the installation process differs.
