Twitter Plug In not pulling URL through to blog

Hi everyone, hope you can help,

We have a twitter plug in which goes from our blog to our twitter channel. This is set up to take the URL of the blog post, and the title of the post and post into Twitter directly. However at the moment it isn’t pulling through the URL, only the title. This doesn’t look that great, as it’s instead a random stream of titles on our twitter page!

Can you help suggest any work-arounds we can try? We have it set up on another blog and it works fine.
