Ron,
I see that your version of iTunes is up to date. What happens when your check for available updates on your iDevices, like the warnings suggest?
The issue you're experiencing is likely due to App Thinning. Updating apps thru iTunes is no longer the preferred way.
---------
iOS 9.2 introduced "App Thinning." This means that apps downloaded directly to your device contain only code and graphics needed on that particular device, requiring substantially less storage space. This is a good thing, but it means the app on your device is not "universal" which makes it unsuitable to be transferred to iTunes and potentially attempt to install it from there to other devices.
