Feature Code not showing in window

HI I’m afraid I accidentally turned on (or off) some feature in GlyphsApp 3 but I’m not sure how to change this? I’m using GlyphsApp 3.1.1 (3148), and now when I open the Features window I see the list of features on the left, but when I select one, I see no code in the main window to the right?
I know the code is there because if I export a TTF it reports an error in the feature code. Also if I open the same file in a version of GlyphsApp2, I can see the feature code fine. This happens as described above in all Glyphs files, so it’s not specific to any code or feature. Am i missing some setting?

thanks

See if you can drag from the top of the empty code view. You might have increased the notes sections all the way up.

exactly that! thanks, all set now. I figured it was something silly but couldn’t figure it out
