i do not find a way to delete or edit Marks. Once we have more than one mark, it seems that the only one editable is the last one. Any other mark set before will stay there FOREVER?

I found some way to do it if anyone is interested. Right click on the marker ( only from the TIMELINE WINDOW ) it won’t work on any other window. Then it becomes the active marker. Then Hold down the right mouse button and you can grab it. From the FRAME menu you can rename the active marker.
Just a workaround, it is still painful.
