Federated Learning android sample app not working

I was following the 'Federate Learning on Android Smartphone' guide from the user guide page but there appears to be some issue with Step 3.) Setting data path on my device. I followed the guide as it was but I am not getting the 'green bar' to select a custom data path. Here's what my screen looks like:

According to the guide, there is supposed to be a way of manually changing the storage location, but my build of the app doesn't show anything. I am on the master branch and running the app on Android 12 if that helps. I am also attaching the logcat output below. Hopefully, someone can help me out! Thanks.
