MinimumOSVersion changes to 4.3 when publishing?

Hello,

I'm having a problem when publishing an app for iPhone using air 3.4 and flash cs6.

I need to set MinimumOS to 5.0, I set it in the InfoAdditions in the app xml, but when I publish the ipa in flash, it changes my xml setting it to 4.3.

This is my infoaditions tag:

<InfoAdditions><![CDATA[<key>UIDeviceFamily</key><array><string>1</string></array><key>MinimumOSVersion</key><string>5.0</string>]]></InfoAdditions>

How can I avoid it? Thank you very much!
