Ghost Theme Deployment success, but theme doesn't update

I used this guide:

I tried changing
uses: TryGhost/action-deploy-theme@v1
to the latest version
uses: TryGhost/action-deploy-theme@v1.6.3

Unfortunately that didn’t work. I get a success on my action, but the theme on my website doesn’t change. How is this possible?

I found the issue, but don’t know how to fix it.
It created the new themes under a different name:

Can I instead override my theme mind-glowing-clean-theme (mindglowing-clean)?

Not sure what I did wrong, but the issue fixed itself after deleting the themes and starting over.
