Android Jetpack DataStore value is not null the first time the app is opened

Question

When using a specific name for the DataStore ("settings" in this case), the Preference value is not null the first time I open the app. But if I change the DataStore name to something different, it will work fine. Any clue why this is happening?

Here's the broken code:

val Context.dataStore: DataStore<Preferences> by preferencesDataStore(name = "settings")

class SettingsDataStore @Inject constructor(@ApplicationContext private val context: Context) {
    private val showPermissionDialogKey = booleanPreferencesKey("isPermissionDialogShown")

    val showPermissionDialog: Flow<Boolean> = context.dataStore.data.map { preferences ->
        preferences[showPermissionDialogKey] ?: true
    }

    suspend fun setPermissionDialogShown() {
        context.dataStore.edit { preferences ->
            preferences[showPermissionDialogKey] = false
        }
    }
}

And here's the working code:

val Context.dataStore: DataStore<Preferences> by preferencesDataStore(name = "my_settings")

// Same as before ...

Note that I just changed the name of the DataStore from "settings" to "my_settings".
