Can't turn BlackBerry Protect off on my Passport.

The time has come to sell my BlackBerry Passport, however Blackberry Project is being a pain.

So if I turn it off on the phone. according to the website it is still on and if I reboot, if comes back on on the device.

If I remove the device from the website, it still stays on on the phone. If I also remove it on the phone, next reboot it turns itself on again on the phone and on the website.

Has anyone got a method of getting this to work?

Phone is a SQW100-1 on build 10.3.3.2137.

Thanks in advance.
