Enhanced interference management missing in latest ASUS RT-N66U firmwares?

Just confirming with the crowd if this was in fact removed or if my router is screwed up. I noticed the option for it is in the HTML source code, but it's disabled.

When was this removed and why? Thanks.

It's been gone for the last two builds. EIM when enabled causes problem to some that's why maybe the option was disabled.
