Removing duplicate permission from AndroidManifest.xml

The AndroidManifest.xml contains these (and some more) permissions:

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />

    <uses-permission android:name="android.permission.GET_ACCOUNTS" />
    <uses-permission android:name="android.permission.READ_PROFILE" />
    <uses-permission android:name="android.permission.READ_CONTACTS" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

The WRITE_EXTERNAL_STORAGE is contained two times. So I remove one and reorder:

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />

    <uses-permission android:name="android.permission.GET_ACCOUNTS" />
    <uses-permission android:name="android.permission.READ_PROFILE" />
    <uses-permission android:name="android.permission.READ_CONTACTS" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

The audio recorder (https://github.com/3llomi/RecordView) normally requests storage access permission and microphone access permission. But after the change it does not request the storage access anymore and therefore the record view does not work.

I uninstall the app from the device for each manifest change to reset permissions. How is it possible that removing a duplicate line causes this?

The merged view of the AndroidManifest.xml revealed that another library also declares this permission with maxSdkVersion="18":

enter image description here

The app was running on API>18, I assume therefore it did not request the permission. Removing maxSdkVersion made the storage permission appear again and the recorder view worked:

<uses-permission
    android:name="android.permission.WRITE_EXTERNAL_STORAGE"
    tools:remove="android:maxSdkVersion" />

My guess is that because WRITE_EXTERNAL_STORAGE was contained two times in the AndroidManifest.xml, the manifest merging process added the maxSdkVersion only to one of them. The other WRITE_EXTERNAL_STORAGE had no maxSdkVersion hence the app was requesting the permission also on API>18.
