Word 2016 Mac CWYW installs toolbar for Endnote online not Endnote X8

I recently updated to Word 2016 for Mac, and was previously running Endnote X7. I have updated to X8.2 today, but the CWYW tab that is installed in Word is for Endnote Online, not X8. My collegue did the same update, and it installed the tab for Endnote X8.

How do install the tab for Endnote X8? I do not want to use Endnote online - I want to use X8!!

I have tried several troubleshooting sheets provided by various sources to no avail, as these deal with the installation of EITHER of these tabs - and I have strictly followed the instructions for X8…only to get to install for online. I have uninstalled and reinstalled Endnote at least 10 times to no avail. Why it doesn’t default to the X8 tab is beyond me, as this is what is installed.

Any pointers on this will be greatly appreciated.

On the Windows version the option to switch between tools is in the endnote ribbon tools: preferences on the "application tab, in Word.    Just not sure it is in the same place in the Mac version.
