IPhone 4 :: IOS 7.1.2 / Icon Appear After Deleting

I have iphone 4 running ios 7.1.2.Recently i got the usual app update of angry birds:star wars.As the automatic app update was getting downloaded,i deleted the app.It was then when things got weird.After successfully deleting the app,another angry bird icon appeared on my home screen showing the loading blue round circle.

I pressed the loading icon to turn it into "waiting",then pressed and hold the app icon to make it wiggle and clicked on x.That is when the things got weird.I couldn't delete the ghost icon and it is still on my home screen.i took the following steps to make the ghost icon disappear but none of them worked. Â

1.I re-downloaded the app from app store but instead got two app icons on my home screen.The clickable and working app icon and the ghost icon.I deleted the original app again and tried to delete the ghost icon by hold n press icon and clicking on x.But no luck.Â

2.I once again downloaded the original app and tried this method of going to settings-general-usage and waited for apps to populate and clicked on angry birds app and pressed delete app.The original app icon disappeared from home screen but ghost icon is still there.Â

3. Long pressed both home button and sleep button to reset the phone.When phone restarted the bloody icon was still there.Â

4. Signed out of app store and tried deleting the ghost icon but no luck there.Â

5. I even reset the network settings.Â
