The dry option is disabled for wool setup


My device is SAMSUNG WD91T984ASH/S2 Waschtrockner (9 kg / 6 kg, 1400 U/Min.)

The problem with it is that on the SmartThings app when i select Wool program, the Dry Option is disabled.
For the rest of the programs is enabled.

Do you know what is the problem?
Is there a special program for wool that includes drying as well?

Thank you
