Why are my custom trace channels not being saved in the project settings?

I need a custom trace channel for my project and everytime I create one, when I next load up the project it hasn’t saved with anything else. I tested to see if the old action mapping settings would save since they are also in the project settings and that did. I’ve looked through some other forum post but I couldn’t find one that had a solution.

same issue

Collision trace channels are saved in [Project Name]/Config/DefaultEngine.ini
Make sure that file is writable, If it still doesn’t save you could try adding the trace channel in the DefaultEngine.ini like so under the [/Script/Engine.CollisionProfile] section:

+DefaultChannelResponses=(Channel=ECC_GameTraceChannel1,DefaultResponse=ECR_Ignore,bTraceType=True,bStaticObject=False,Name="TestTraceChannel")
