There are fewer presets in the new Metal type yes. The "Metal IOR" parameter changes only the IOR of the metal (internally the nD and K values). So it's not a bug.

You can add more presets yourself by editing the Metal.xpr preset file in any text editor, found in: C:\Program Files\Next Limit\Maxwell 3\extensions\presets
You can easily see how to add another preset to that structure.
