Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

You need to not only filter the list, but also return the result as a list of ints. You currently return a list of objects, and tests don;t like it.
Description for statically typed languages could use some clarification here.
