When searching for a creature by creature type, the results are incomplete. This occurs because creature types that have been updated on older cards are not appearing.

For example, Rootwater Alligator is still displayed in Oracle on the app to have the Alligator creature type. On desktop, Gatherer correctly shows it as a Crocodile creature type.

This current feature is annoying, as accessing Gatherer on mobile asks me to use Companion, but I can't rely on the data on Companion until this is fixed.
