Unpot the darn thing ASAP & pls. show us the roots.

Shake off the mix & look at their condition; also take a sniff -- anything smell like rot?

A plant mentor of mine used to say that trying to diagnose a plant w/out checking the roots is like trying to see while wearing a blindfold.

Roots are no good. The wet soil has been removed. How do I proceed?

I'd remove every last bit of soil.

If the bottom of the stems are firm & not rotting OK, I'd leave the cuttings out to dry a few hrs. & then place into a glass of water (just an inch of 2) to try & stabilize them. You'll need to wash the pot, sterilize everything & go out & get new mix to repot in a day or 2.

I'd sprinkle household cinnamon at the bottom of the stems & then shake it off, & let dry several hrs. Cinnamon is a natural anti-fungal & MAY help hold off further rot.
