"Bestiary Monster Creation" and Familiars
 

So, one of the members of my Pathfinder group made a very specific request at me for a familiar. Well, not that specific. It's basically that she wanted to add flight to her "viper" familiar. Now, I figured I'd take it up a notch and create a new monster that featured some of the traits of the viper and some of the traits of the faerie dragon. But I have just an awful time with the editor every time I give it a shot, so I figured hey, why not go with that new thing they added?

I clicked on the box for "don't limit companion races" or whatever it's called and picked "Bestiary Monster Creation." And it sort of worked? It looks like this.

See, there's no scroll bar over there, so I can't actually edit the whole thing. And there's also maybe like a gap on the bottom? Like perhaps there's actually nothing else? It works with a scroll bar and everything when I'm working with a not familiar character.

Anyway, is there any way to fix this, or at least circumvent this? Any help would be appreciated.

Just a note that adding "Flight" to the viper is actually really easy. Just go to the viper familiar and then go to the "Adjust" tab. The 3rd set of adjustments has one where you can add a "Movement" type. Select fly and set the counter to the speed. Boom all done. :)

As for the gaps and stuff I can't help sorry...
