Lost almost all pen variety after update

Hiya! I updated the app recently and now my pen selection has been reduced to about 7 Normal pens and about 4 wacky colourful ones. All of the sections like pencil and paint or ink have disappeared as have my favourites folder too! This is sooo frustrating as I can't draw with any of the pens I'm used too. Cannot find a way to fix! Plz help !!
