Steps to reproduce
Place one of the new flowers in a crafting table (cannot be a 2 block high flower or a poppy)
Place a dandelion in a crafting table
The new flowers (e.g. Blue Orchid) will only give 1 of their respective dye, whereas the dandelion or the poppy (the new roses) still give 2
Bug is that dandelions and poppies give 2, not that the new flowers give 1.
Confirmed.
