A:

This can happen if both your applications are using different-different Bundle Identifier. Which means the version which is on web url is using different Bundle Identifier and currently you are using different Bundle Identifier.
There's nothing wrong in that. Hence, your device is treating them as two different Apps. And not replacing the old one.
Just delete both the application and download it again.
