Hi Rufty,
We checked it on OS X and on Windows 10 and it worked as expected for us. Try refreshing Studio One's application settings to see if it works after that, and if not, please create a support ticket so that one of our support representatives can assist you in figuring out why this new feature doesn't work correctly on your system.
==== Refreshing Settings ===
1. Go to Help>Open Settings folder.
2. Copy the contents of the folder over to a folder on your desktop.
3. Close S1 and delete the contents of the settings folder with the exception of the user.license file as well as the "Extensions" folder.
4. Open S1 and go to Studio One>Options (Preferences on a Mac) to reconfigure your settings.
5. Test to see if the problem is resolved. If it is not, please feel free to copy your settings files back over from the backup that you created in step 2.
*If you are missing presets or Sound Sets after doing this, simply double-click one of your Sound Sets under Documents>Studio One>Sound Sets.
