Thanks Rikk..........
Internal groans and laughter here! That's exactly WHAT I UNDID!!!!!!!!!! I activated the library filter, and on the "Label" pane, I replaced label with Metadata status (never even LOOKED at the label data) - which didn't work, then opened text and tried putting in the label names, which didn't work, then I did a search through all the menu pulldowns, then an Internet search.... Had I actually LOOKED at the data in "label", I'd have saved myself a lot of fiddling and a bit of embarrassment!
Off to change a LOT of labels!
