Another applications folder is getting created under Applications in mac

My CC extension should be installed into the /Applications folder.

Instead of this, a new Applications subfolder is being created inside the /Applications folder. extension is being installed into that new subfolder

Can you tell where I am doing wrong

My mxi looks like this:

<file-tokens>

    <token name="apps" definition="/Applications" />

</file-tokens>

<files>

<file source="contents/ArtOptimizer.app" file-type="ordinary" products="" platform="mac" destination="$apps/ArtOptimizer" />

<file source="contents/ArtOptimizer_User_Guide.pdf" file-type="ordinary" products="" platform="mac" destination="$apps/ArtOptimizer" />

</files>
