cant select extra fine

[thoger0 0]

I cant select the "extra fine" resolution in Cura anymore. Suddently it just isn't available to select. It's still there in Cura, but clearly it's greyed out. Why? 
I'm using ultimaker 3, with brand new 0.4 AA and BB  nozzles installed.

The availability of the profiles depends on the selected material and the print cores.

For example when I use TPU as material I have no extra fine enabled, but when I change to PLA it is selectable.

Hi Smithy, thanks for the quick reply! 

I have Ultimaker tough PLA in the AA core and generic PVA set for the BB core. I'll try with a normal PLA instead and see if it'll allow me to select the extra fine. 🙂

What materials do you have active? If you try to combine a non-pva material with the BB nozzle you get into a not supported state.
