Select several categories or subcategories in sidebar

Hi there! If I am not mistaken it was possible to select more than one category/subcategory in the sidebar so that the font window displays the group of characters that belong to them (e.g. select only Parenthesis and Quotes instead of the whole Punctuation category). I used to to do so by pressing the shift or command key to get a multiple selection. The thing is that the selection can be done, but nothing is displayed in the font window when more than one category is selected. Is there anything I am missing?

I’ll have a look. But that never working like that.
