Page Editor - Package Listings issues in TNEW

I am trying to help edit a Page Editor - Package Listings page on Test TNEW admin, and there is some stuff in the form fields right now, but no matter what we do (including removing all of it) we get a Failed to Save Component message when any changes are made.

Has anybody bumped into this before? We have a RAMP ticket open but they are moving a bit slow and we are trying to do a Prod copy tonight. Any help is greatly appreciated!
