Problem with particle LOD

I’m trying to do some particle LODs, but I cant edit the modules. The EPIC documentation says:

https://udn.epicgames.com/Three/CascadeUserGuide.html#PartileSystemLODs

But I don’t see the “Enable Module” option, here are a screenshot:

The particle I’m trying to edit is a copy from one included in UDK, TorchFire01, but I was trying with another new and the same problem.

the doc is wrong (probably just very outdated), what you want is “Duplicate next higher LOD”

Yes, it worked, thanks.
