When creating homebrew racial trait options of a homebrew subrace, clicking the "EDIT" button to go back to editing the race as a whole will give you a "not found" page. I looked at the URL and changing "race" to "subrace" in the URL fixes the issue. Please rewrite the link in the "EDIT" button so that it works properly.

My specific instance: at https://www.dndbeyond.com/entity/racial-trait/3169019/racial-trait-option/create, clicking EDIT attempting to return to editing the subrace causes the issue.
Nice catch! I am able to reproduce the issue on your homebrew as well as my own. I will pass this along, thank you for the report!
