Illustrator 2018 CC 22.0.1
Mac OS El Capitan 10.11.6

In the past using with CS5, I was able to select multiple swatches in the colour panel, double click, and then change properties such as “Global”. As per the video in AI CC 2018, I select multiple swatches, double click, and it only opens the panel for the colour I clicked on. I’m only able to change multiple colours by clicking on the Swatch Options.

I don’t know if this is a bug or a feature that was dropped, but it would be nice to have it back for more efficiency.
