Are you really running 2.1? If so, did you upgrade?

This is a new-ish option, but there's no reason for it to be missing. Ensure that you have all the latest files uploaded (you can use the file health check in the control panel) and then go to <url>/install/ and choose to rebuild the master data.

Running 2012 and this started after upgrade. Health check success no missing or unexpected files or content.
