Hello. I think the one that was activated would be the AI Enhancer channel map, which is a new feature related to our new AI Enhancer feature. You need to have this channel map in order to use this feature.
I thought, an unchecked “channels”-box means everything inside channels will be unchecked. (maybe this happened because i updated this file to version 2.8 and so AI enhancer was on automatically?
Currently it will be checked by default, but you can also uncheck it if you render images that don’t use this feature. I have feedback with our team about your needs and they will discuss this.
