Double Up of Joints in Rig

[gaultsoph]

I think I made the mistake of copy-pasting or trying to duplicate the bony rig and now I have a double-up of the outlines for the moveable joints, though not of the rig, as far as I can tell. How can I get rid of the double up of the joints, for instance, I can see 2 of the outlines of the hip joints? It makes it hard to manipulate anything in the graph editor as the double-up seems to show in the graph editor with different movements, making it more difficult to sift through. New to Maya so unsure what to do.

--I tried reuploading the reference after I deleted it. The joint outlines still appeared but they weren't tethered to a rig, whereas before they moved with the rig.

hide/delete irrelevant/broken elements, that are not References. nothing special there.

I've tried deleting each element separately and nothing seems to have worked
