Hey there, so sorry to hear about the issue! Can you try uninstalling and reinstalling the extension? There's some additional validation on the settings I had to add to resolve some bugs, which is causing this issue. Feel free to file an issue on GitHub (https://github.com/arimgibson/deadname-remover) or shoot me an email at hi@arimgibson.com to get some more troubleshooting help! ~ Ari
