IonInput floating transition is not working properly

Hello everyone,

I am completely new to Ionic and created a new project using AppFlow.
I want to made some IonInput Fields with a floating label but sadly my transitions are not working.
Here is the Github Repo GitHub - smox/test-ionic

If you clone this repo, start it with ionic serve and click on the two inputs or type something the transition of the labels are not working.

Has someone an idea how to get rid of this problem?
