Internet Explorer 10 GPP drops setting for Protected Mode

Hi!

I have a problem with enabling Protected Mode for Internet Explorer 10 with GPP.

I can enable the Protected Mode but when I´m opening the GPP for Internet Explorer 10
it sometimes (most of the time) removes the setting.

This means that everytime I have opened the GPP I have to do a test
on a client computer to see if the setting still is applied.

I´m editing the GPP from Server 2012
