Quadrant chart not working

Hi,

I've added the quadrant chart into Power BI but for some reason it isn't working.

It keeps saying 'Please select legend axis value', which I have done.

Any ideas?

I suppose it could be an error with the addon download?

I downloaded the sample pbix from MAQSoftware and that's working fine.
