Trial version not letting me design certain punctuation

Hi Guys, I am coming to the end of designing my font and have noticed punctuation is missing some boxes which are pretty essential such as apostrophes, question marks etc. will these become available once I purchase the licence or am I missing something?

Have you tried clicking the plus at the bottom of the font tab and typing the name of the glyph you want to add?
“question” for question mark
“quoteright” for apostrophe
I am on trial currently as well.

Have you seen this: https://glyphsapp.com/tutorials/adding-glyphs-to-your-font

Thanks guys I realised when I right clicked it revealed the missing glyphs.
