Secrets not deploying to all machines in my app

I am having an issue where whenever I try to deploy secrets - it only updates a single machine - and not the entire fleet?

Is there any logical reason for this? I’d like to be able to just deploy my secrets and have them go to all my machines without issue.

Apologies - found the answer in the docs. I created them with the API and therefore they are detached.
