Auto enable on custom post types

Thanks so much for fixing the email notification bug, this is a very essential feature for such plugin!

Another quick question: when I am on settings > custom post types, I can set settings for the particular post types, will these settings overright any settings i set in the “main” settings of the plugin?

Also, can you explain more in details about the “auto enable” feature? see this screenshot: https://prnt.sc/5RYBFLKxJxTu
If I enable this feature, what exactly will happen when my post expires?

(Sorry for asking this exact question in the email notification thread, you already marked that thread as resolved and I was not sure if you get to read that thread again.)
