Default App update problem

Trying constantly to update the gunship 3 app. The total size of the app is over 200mb. The update only packs in at 32mb.fine thought it was a delta update. App doesn't load. So I removed the app totally. On the reinstall the app only downloads the same 32mb and not the initial 200+.mb. Strange. Does exactly the same on my nexus 5. Almost like it is not deleting all the original files. Tried es Explorer to have a look about but no joy

Thanks for any feedback
