Hi David,
Sorry for the trouble here!
I tried renewing one of the my test licenses on the My Account > Licenses screen and it seemed to add the correct level license to the cart.
Just to confirm: are you clicking the blue “Renew License” button next to the license key number?

The reason I ask is because there are upgrade links right below it and I know it is easy to mistake those as the renewal. In fact, I’ve seen other threads posted in the past regarding the same thing.
Please let me know and I’d be happy to keep looking into this with you.
Cheers,
Geoff
