Firebase overwrites asyncstorage

I have been using AsyncStorage to store some device settings and test data for my app. I’ve recently added Firebase as an auth/database layer. It seems to have overwritten everything in my AsyncStorage to store it’s auth.
Is there a way to use Firebase without it overwriting my storage? It’s not a dealbreaker but it is mighty inconvenient since I don’t have the database setup for the app data yet as I am in the middle of testing auth.
Any help would be appreciated!
