Landscape Grass Type Scale settings.

Seem to be quite frequently getting some kind of bug with the x,y,z, min/max scale settings in the Landscape grass Types.
All of a sudden no matter what the scale settings are in the Grass Type everything in the scene is just displaying at default 1.0 scale and the settings become completely unresponsive.

the only way I’ve managed to get the scale settings functioning again is to delete and completely recreate the Grass Type…

anyone else experienced this or know a fix for it? the frequency at which this keeps happening makes the min max scale settings pretty much unusable as its just too much constant rework.
