Why on z-suite i dont see z-flex

good morning,
i can’t understand why in z-suite for inventure i can not see z-flex filament but only semiflex (i think the material is not similar, and also i think on z-flex the retraction and the fan speed must be off)
but on the printer u can choose this filament.

Hi Ugo,
switch to single spool mode. Z-flex is selectable in single spool mode, z-semiflex in dual-spool mode only.
