Seeing this problem, myself, with all my SuperUser rights, in on-prem 14.2.
Neither work-around works. Also, tried putting my own name in template and in new project when creating - didn't work, either. And, whey trying to use 'copy from template' from action pull-down, getting "Error 501 - Not implemented. The server does not support the requested feature..."
Even when creating my own template and trying to create/copy from my own template, I still get the errors.
There is no work around.
Please, Nick - tell me how a known defect like this, where the feature is still present and clickable, doesn't get fixed?
Very frustrating....
