Hi all (but especially Paul the content creator of this course)
This course has some missing information in Level 43, which means that the Level (and hence the course) cannot be completed.
The help information about this issue states: Sometimes, users will accidentally leave blank columns or miss translations out when creating a course. This will cause an error on Learn New words as there is an inconsistency between the number of items to learn and the ones that are able to be shown in a learning session.
If you could check the level and amend the level, that would be great
Cheers
David
