I'll guess that if reset x-form was applied and you have no other problems with the polygon surfaces in question, then you might try the distribution rollout
I've had some surfaces refuse to work, even after reset x-form and had to redo them.. A lot of the problem surfaces, if created in Max, are fine, but occasionally you import something like a surface, modelled in another program, and no matter what you do, forest pack refuses to scatter correctly.. Rare that I use imported geometry though, so not really a problem
What I find strange about your screen shots though, is instead of showing the setting of the forest pack object, you have a huge area showing rappa tools. Surely if you had the forest pack pro setting for you FP object on screen, it might just help people solve your problem... Oh and in order to get them all open and showing on screen, you can increase the area of the screen that the dialogs take up. 1 column, 2 columns, 3, 4 even 5.. very useful for screenshots and you can easily reduce the number after taking the screen shot.
