pulumi preview --diff

nor

pulumi up

shows the detailed diff for my deployments. For example, when my actual diff is an image change all I see is:

~ kubernetes:apps/v1:Deployment: (update)
      ~ spec: {
          ~ template: {
              ~ spec: {
                  ~ containers: [
                      ~ [0]: {
                            }
                    ]
                }
            }
        }

I'm on version 3.1.0 for pulumi, and my npm libs are

"@pulumi/kubernetes": "^3.0.0",
        "@pulumi/pulumi": "^3.0.0",

this happened before the 3.0 upgrade but i only decided to ask about it now. Anyone know what's going on and how to fix it?
