This was a problem in Safari (an other similar browsers I presume), but not in Firefox: hovering over the grammar comment (shown below the grammar name when you edit a grammar) didn't reveal the button to edit it, thus preventing you from adding a comment. It was till possible by selecting the "Enable editing on touch devices." at the bottom of the screen, but most people probably didn't notice that it is possible to add a comment.
