Express: "My looks" are gone after update to 4.12.2018

After updating to version 4.12.2018 on iOS 10, all my user created looks are gone! I have been working on and with them for over a year now, so: how can I get them back? I am logged in into my account ( also using Photoshop CC and Lightroom CC), so maybe they are somewhere in the cloud, but just not accessible after the update? Any help is greatly appreciated !
