Studio One should be compatible with multi-touch on Windows 10. Unlike the Mac version, there is not something that needs to be enabled. Multi-touch on Windows is driven by the driver for your multi-touch monitor. You may want to try re-installing the latest version of the multi-touch monitor. On the Studio One side of things, you will want to try removing your settings files from the program and re-configure Studio One. Here are instructions:
Go to Help>Open Settings folder.
Copy the contents of the folder over to a folder on your desktop.
Close S1 and delete the contents of the settings folder with the exception of the user.license file as well as the "Extensions" folder.
Open S1 and go to Studio One>Options (Preferences on a Mac) to reconfigure your settings.
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.
I will create a tech support ticket for you to continue troubleshooting the issue.
