Problem solved. The "group presets with catalog" button was selected. once I selected everything went back to normal. The odd thing is, I didn't make that selection... It just happened.
"Greeted out" was a typo - should have read grayed out. Thank you iPhone predictive text and not allowing the Canadian (correct) spelling of Grey.
Time machine prooved handy in fixing the issue. Thanks for your help.
DE-SELECTED the group presets with catalog button.
