Thanks for your question.
In general we don't have option to hide step name as each step should at least include name and description and expected results are optional fields.
We shifted to Markdown within description and expected results fields due to the number of customers requested for that as in most cases users do need to have the RTF options within these fields.
Having said that, we highly appreciate your point of view and we will consider option to turn off the Markdown within these fields in the future.
Will keep you updated
