InTune unable to enable Automatic Registration

I am trying to enable automatic registration inside intune. Currently all fields are greyed out and I am unable to click anything. There is a warning at the bottom of the page "Creating new WIP without enrollment policies (WIP-ME) is no longer supported." I am unable to find useful information by searching, I believe I already have enrolment policies in place (unless I have messed up, which is always a possibility).

In documentation and tutorials I have seen they often have the same warning at the bottom however the page can still be interacted with (not greyed out) so I'm at a bit of a loss. I have been stuck on this issue for a few hours now. Any help would be greatly appreciated.
