Android : Android Studio 0.8.0 error "Failure [INSTALL_FAILED_OLDER_SDK]" when trying to load app on phone

I am in the process of building and debugging an app on my phone and I keep getting the error "Failure [INSTALL_FAILED_OLDER_SDK]" when I try to push a test build to my phone. It by default set the target SDK to L but I set the minimum SDK level to 9 to cover the most devices. The device I'm trying to load the app on is a Galaxy S3 running 4.4.4 (which I know is API 19).

Here is the defaultConfig from my build.gradle

    defaultConfig {
        applicationId "com.tg94.intcalc"
        minSdkVersion 9
        targetSdkVersion "L"
        versionCode 1
        versionName "1.0"
    {

When I go and look at my AndroidManifest.xml though, this is what it shows

    <uses-sdk
        android:minSdkVersion="L"
        android:targetSdkVersion="L" />

When I try to edit this (I tried editing in Visual Studio 2013, Notepad++ and just plan Windows Notepad), I noticed the android:minSdkVersion always changes back to L even though I changed it and saved it to API level 9. Is there any suggestions I should try to fix this?
