Android App name cannot display correctly

Hello experts, I am developing a app using the Eclipse. Today, I found my app name and icon cannot display correctly when I install the app in my Android phone. I have checked my Mainfest file, I thought everything is OK. I need some help thanks.

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/MyTheme" 
        >
   
        <activity
            android:name="raiduswaikato.radiusmedical.app.MainActivity"
            android:configChanges="orientation|keyboardHidden|screenSize"
            android:icon="@drawable/circle"
            android:label="@string/blank"
            android:screenOrientation="portrait" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

That is application tag in the Mainfest file. Is there anything wrong?

When the app was installed on the phone. The icon was displayed as the android:icon="@drawable/circle" which is the mainactivity title icon. And the app name is blank which is also the mainactivity lable.
Why the application tag does not work?
Thanks.

Hi T.Tailor
     When I delete the android:icon="@drawable/circle" and android:label="@string/app_name", the app seems correctly. But the MainActivity's title and icon become to the app's name and icon. That is not I want.
    I need the app shows a name and icon, also the mainactivity shows a name and icon. They are in different. Do you have any solution about that? Thanks for your answer.

Hi Krunal T.Tailor
    I have solved my problem using the activity-alias.
        
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/MyTheme" >
        
        
        <activity
            android:name="raiduswaikato.radiusmedical.app.MainActivity"
            android:configChanges="orientation|keyboardHidden|screenSize"
            android:screenOrientation="portrait" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        
        <activity-alias
        android:targetActivity="raiduswaikato.radiusmedical.app.MainActivity"
        android:name="raiduswaikato.radiusmedical.app.MainActivity"
        android:label="@string/blank"
        android:icon="@drawable/circle">
          <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
          </intent-filter>
        </activity-alias>
