I think it can be also because Sketch changed way they sort the symbols. For example, when you used _naming, it was last on the list; now it's first. God knows how many things like that was changed...

However, I like overrides indentation, that's handy. :)

Michale, it was short when style sections worked properly :) Now it's basically unusable as it shows the name of the first style in a row. :/

Well... I just hope this is bug, not feature.
