Office 365 subscription changed to MS Office Pro Plus 2016

After upgrading to 20152.1 my Office 365 has changed to MS Office Pro Plus 2016 and is requiring activation
If I select Change license option then my valid MS Office 365 license is presented but nothing appears to happen when I select it and click next (it stays as MS Office Pro Plus 2016)
I have tried both online & offline Office repair
I have uninstalled Office 365 and reinstalled
How do I revert to Office 365?
What has happened?

I have both licenses on my account, if it was me I would try this if you have not already done this:

1. Open Word, and sign out (it may be top right corner, find your account avatar, click it, the I see 3 dots, click them and click 'sign out'). It may be somewhere else on Word 2016. I think it's important to be signed out of Office.
2. Uninstall all Office apps
3. Go to Office 365 Login | Microsoft Office, sign in with your account that has the 365 subscription, and install Office 365, then activate it. You can see exact instructions here - https://support.microsoft.com/en-us/...2-23adc4716658.

Rolled back to 20150 and issue still there!
Ran Office 2019 and Office 2016: Activation Troubleshooter which appears to have fixed the issue
