Some components can't be added to a glide sheet?

I’m missing quite a few components. Am I missing something here?

I’m using a “Details” layout here.

Issue Solved:

I added a non user column and it unlocked all the components. I assumed components that allow “custom” values would be available even if all columns on the sheet were user only…
