sudden extra text on Multiple choice connector

Hi

I've been working on a Xerte LO which includes Multiple Choice Connector pages to test comprehension and control progress. This was all fine and I was just doing some final user testing when suddenly some extra red text appeared after each answer on all the connector pages. Please see attached.
Have I inadvertently ticked something I shouldn't?
Any suggestions anyone?

Thanks
Vicky

This happens when you added 'Add Author Support' to the Learning Object (Highest level icon) and switched that on:

Wonderful, thanks Tom.

I must have caught it by accident.

Thanks again
Vicky
