Where does the Content Threshold come into this though? That only applies to Content Type formats when changing folders. It has no effect on any other format type, which is why it isn't shown for the others.
I guess the column inheritance checkbox could be useful in Favorite formats purely so you can define what the checkbox is you copy and paste a Favorite over another format in the Preferences list. But there's no other time, at least that I know of, when that checkbox would do anything for a Favorite format; it would never be used directly, because selecting a Favorite format when looking at a folder will load that format as-is without ever inheriting columns from other formats.
From the look of your tooltip screenshots above, neither the Favorite formats nor the Content Type formats were in play, so they shouldn't have been where the Attributes column was coming from. (That must be coming from Default Format > User Default at the bottom of the list, unless something strange is happening.)
It's also sometimes less confusing to test formats by closing the window (or at least the tab) and opening a new one, to ensure nothing done to the previous window is still having any effect. (Mentioned near the bottom of Folder Formats: Quick Guide just before the video.)
