1. In my quest for grammatical consitency, I like for all words in a title or command to be capitalized. So, I went into the settings, and into movies submenu.
2. I chose "Update library" and went to change the label to "Update Library" (all I did was change the lower case l to an upper case L).
3. I also did the above to the TV Shows "Update library" and the music "Update library".

@robertlaing, where exactly did you change this? There's not much I can do if you manually edited the "settings.xml" of the skin.  And also, the strings I am using (Update library, Stop scanning) are not provided by the skin, but by Kodi itself, so they would need to be modified in Kodi core in order to achieve your desired grammatical consistency.
