Look at the bottom of page 1.
Bug #2) If you want custom styles to show up in the styles list of the editor you cannot save your settings as a preset. The minute you check "save as preset" and give them a name you will loose your styles.
Confirmed by Dani Chankhour.
And as described abowe I cant have custom styles when using a preset.
