I'm sorry to be so dumb. When you say "tag editor" where do you mean? In the "Tags" field I can right click on a book. I then select "Edit Metadata." Then I select "Edit in Bulk". I use the drop down menu on the right of "remove tag" and select an offending tag I want to delete. I hit return and.... it has no effect. What am I doing wrong?

Thanks for your patience.
