Freelinking: Create new content not working as expected

Hi, I'm struggling with the Freelinking module at the moment, version 5.x.1.3-beta2. I've created a test page with some double-bracketted phrases inside, then used this to create the linked pages. However, I notice that the freelinks page still shows "Create this content" against the links, even if they've been created.

The link to create is also broken, showing only the first word of the double-bracketted phrase.

For example, the "Main Page" link actually reads - mysite.com/node/add/wiki?edit[title]=Main

I also tested this against a single-word phrase, and it still doesn't register the content as created. If you try to create a wiki page and submit it, you get an error saying "A page with this name already exists". I had a version of this running under Drupal 6.2, and it worked fine, but in 5.7 it's more troublesome!

Just wondering if anyone else has experienced this issue or how to resolve...
