Circular menu help

Hello,

I have followed the following tutorial to the letter (as far as I can see):

but mine doesn’t work.

When I have made it I can only see one of the buttons not all 4 (please see attached).

It’s driving me nuts trying to figure out where I’m going wrong!

Any help would be very very appreciated.

Thanks
