App Store updates problems

Hey guys!
My new iPhone 6 plus is experiencing a strange thing regarding App Store updates. The thing is that it shows that an update is pending for an app that isn't installed on my iPhone, it's not even available in the App Store, only in the U.S. App Store. I would delete it from the phone and from iTunes, but it doesn't show up on my PC. Any advice on how to solve this?

Thanks

Here is a screenshot:
(The App is called "Hilti Screw & Nail Selector")

 

Maybe a possible solution would be to have someone in the U.S. Download the app, then send me the raw file via email. Then I would add it to my iTunes manually, then update the phone, then delete the app from both the phone and iTunes on the computer.
