Manage ubuntu server deployments Katello

Problem:
I have deployed a katello 4 instance on Centos Streams 8 to manage the ubuntu machines in our environment.

When i go to the host registration and try to input the details to generate the registration key the generate option is greyed out and i am unable to generate the string

the error is " Invalid field: Activation Keys"

Ubuntu does not require activation keys however it will not allow me to progress.

How do i get around this?

Foreman and Proxy versions:
3.3.0-develop

Distribution and version:
Centos Streams 8
