I've just had a look since and Justin is right. It might be best to get in touch with US support if you're still having issues.
When looked a different profile (launchpad-americangirl) when it tried to import the library it flagged an error indicating two E-Commerce extensions aren't possible:
I would test the 'launchpad.thomaswood' profile but in order for the library to be re-injected I'd have to save and publish a new version of the library (which I don't want to do as I don't want to interfere with your implementation).
- Make a note of the E-Commerce extension settings in your 'launchpad-thomaswood' profile
- Delete it and save the version
- Save a new version and publish your library (ensuring your E-Com extension is configured as you'd like)
- Open the 'launchpad-thomaswood' profile.
If that isn't importing the E-Com extension then definitely get in touch with your local support or Account Manager
