duplicateParentState works on one nested View but not another - Android Q&A, Help & Troubleshooting

I have two LinearLayouts that are focusable. Both of their backgrounds are set to a selector that loads an image when they are focused. When they are not focused the background is set to transparent. These both work perfectly fine.
Nested in each of these LinearLayouts is an ImageView whose src attribute is set to a selector. This selector also is set to an image when it is focused, and is set to transparent when it is not focused. Both of the ImageViews have duplicateParentState="true". The ImageView in the 'first' LinearLayout works as intended. It shows the image when it is focused, and is transparent when it is not focused. However the 'second' LinearLayout's ImageView does not work. It remains transparent and doesn't load the image. It seems to never properly inherit the focused state from the LinearLayout.
I have another similar section in another part of the app that has 4 of these LinearLayouts with nested ImageViews that do the same thing. Even there, only the first one receives the focused state from the parent properly. All of the others do not.
LinearLayouts and ImageViews:
Code:
<LinearLayout
android:background="@drawable/background_selector"
android:focusable="true"
android:focusableInTouchMode="true">
<ImageView
android:src="@drawable/image_selector"
android:duplicateParentState="true"/>
</LinearLayout>
<LinearLayout
android:background="@drawable/background_selector"
android:focusable="true"
android:focusableInTouchMode="true">
<ImageView
android:src="@drawable/image_selector"
android:duplicateParentState="true"/>
</LinearLayout>
LinearLayout's background selector:
Code:
<selector xmlns:android="">
<item android:drawable="@drawable/background" android:state_focused="true" />
<item android:drawable="@android:color/transparent" />
</selector>
ImageView's src selector:
Code:
<selector xmlns:android="">
<item android:drawable="@drawable/image" android:state_focused="true" />
<item android:drawabe="@android:color/transparent" />
</selector>
The background attributes on the LinearLayouts work perfectly fine, but the src attribute on the ImageView only works on the top LinearLayout.
