Bugs in the Properties panel
In Illustrator CC 2018 (Windows), the Properties panel does not scale in width, so it can not be grouped with other panels (when switching, all panels become equal to the Properties panel in width).
In the transformation section of the object in the Properties panel, you can not change the size proportionally using the Ctrl + Enter shortcut. In the Transformation panel, you can do this.
We have the fix available in the latest release. Please update Illustrator using Adobe Creative Cloud application to the latest build for version Illustrator CC 22.1.
