After updating to Version 0.16.0 the large flowers, like sunflower, let only fall one item instead of the two previously.
That's just in the survival very annoying.

This may be not a bug.
Other flowers you can breed with bone meal, large flowers do not.
So how should you get large flowers in survival?
Large flowers can still be 'bred' in survival by using bonemeal on an existing large flower Falko Finster - that they could ever be duplicated without any resource input was definitely a bug.
Dropping 2 items was a bug, it was fixed in the update: MCPE-13304
