plugin notes name

Right click-> Select-> All similar elements-> Del
It should work. Welcome!

I'm guessing you used staff text to add the note names. Select the section where you want to remove the note name (or select nothing for the entire song) and right click a note name. Click select All similar elements in same staff and press delete. NOTE: this will remove all staff text from that staff, but replacing it is probably faster than deleting each name individually. You can actually unselect anything you don't want to delete by holding ctrl and clicking the item and it will turn black so you know it is not selected.
