Glyphs 2 - Font window is blank at open

If I open a font and go to the ‘Font’ window, it is blank, (the Category is ‘All’) the glyphs display only if I select another category. Going back to ‘All’ will display all Glyphs again.

(2.0.0 on 10.8.5)

Maybe related: I find if I’m looking at a list filter, then click on Letter under Categories, the grouping of the glyphs I see in the main pane of the font window is strange: it starts out with “Letter, latin” but only shows the glyphs in the previously selected filter list. Below that there’s a grouping with the same label that has the rest of the letters.
