Lens registration greyed out options

Hi,

Using the Rokinon 12mm on the X-Pro2 and setting up the lens as #5 on the lens registration menu, I can set the focal length but all other options are greyed out (distortion, color shading and peripheral illumination).

I don't really feel the need to enter them right now, but I wonder what other options could cause this, or if it has to do with the lens itself. I think I remember the profiles exist in Lightroom for automatic correction for the 12mm. Could it be linked?

Thanks for...
