Jenkins 2.246.2 - lost build "parameters" menu item

[alan.l...@gmail.com]

I have a couple of Jenkins instances running 2.246.2.  I configure both from an AMI that includes a JCasC YAML file to set role permissions and assignments.

I noticed today that, on a build page, the "parameters" left menu item is missing.  The funny thing is that it appears on the other Jenkins instance, same Jenkins version, same Java, same Jenkins.yaml for the JCasC config.

Am I missing a permission somewhere?  Is there a permission that controls whether the "parameters" menu item appears on a page?

Thanks for any guidance.
