I´ve done 15 flushes so far in two of them I pushed only white stones, with the exact description of yourt post, ie.e., waxy, yougurty like, soft and greasy.
According to Mrs Chang-from Sensible Health, these are cholesterol stones. Every time I push these type of stones I feel good.
I guess they are from the liver not from the gb.
I never had ACV and still I´ve pushed lots of these stones.
