Hi @Nikki_Kamps, welcome to the Asana Community Forum!
If the template was set as comment only and the only user with edit access has left your Organization, you won’t be able to remove it. In this case, I recommend you contacting our support team as they can see more details about the project and give you alternative solutions!
Please share the URL of the project and this thread with them to speed up the process.
I hope this helps!
