Page names no longer included in component names in new files?

I’ve been working in the same published library file for over a year now. In the Assets panel, all the components inherit their Page names in the accordion structure. However, I noticed today that in all the newer files I’ve created and published components from do not do this. The page name is just skipped altogether.

The problem is that I see no toggle for this option anywhere. It seems like a new feature to library files, but so far the only way I have seen to get control over this is to just work in an older file for the Page names and a newer file to ignore the Page names.

Is it possible that this new default function was accidentally added without the option to choose being added yet? Or is this just the new norm for library organization?

Any thoughts appreciated! - Matt
