Clear contents of primary field in collections

Sure. Shown is the collection I want to clear entirely, including the Title field. Deleting it is not an option, and right-clicking to delete rows (which is cumbersome to begin with) does not seem to be possible. I want to clear the Title field because it was populated twice from an imported csv file by mistake, stacking duplicate data that don’t match up with the rest of the columns.


Thanks for your advice on this issue.
