I had a look at this issue and can replicate.

It is removed as expected in the front-end, it also does not take part in the save-payload, but once saved it comes back from the server. Indicating that the server did not remove it.

@nhudinh0309 I just merged PR #21585 which should fix this.
It would be nice if you could verify the fix once it is available in the prerelease feed. 🙂

@lauraneto Tested on the release/17.2 branch, I can now delete root properties in element types, document types, member types, and media types without any errors ✅

Thanks for confirming @nhudinh0309, and for the review @lauraneto. I'll close this one then now.
