Food Processor Help

So this is totally random, but I wanted to ask my readers a few questions about food processors. First of all, if you don't use one or don't know what one is, just quit reading now. However, if you have one and know how to use it, keep reading.

I bought a brand new KitchenAid 9-cup food processor last Saturday for ONE purpose: making homemade whole-wheat pizza dough. We were having friends over for dinner (to make pizzas) and I needed to make at least two batches of dough. The 3-cup capacity food processor that came with my blender/food processor combo unit was NOT overly suitable to make this dough, and certainly not a double batch of it. While I knew I wanted it specifically for the dough, I also knew that it would come in handy for several other recipes, especially the more I try to get away from processed foods and make more from scratch.

I was totally stoked to put it to use once I got it home and all washed up. I had my King Aurthur white whole-wheat flour, yeast packet, salt, olive oil and water ready to go. With this particular pizza dough recipe, you're supposed to pulse the water, yeast, salt and oil together. I followed the instructions and did so. I immediately noticed the water seeped out of the bowl where the lid and bowl meet when I turned the unit on. I guess it made sense that it's not a tight seal, and it would be possible for the water to leak there. I figured the mixture was pulsed enough, and went ahead and added the 3 cups of my expensive $9 bag of flour and turned the food processor on. Almost immediately, I noticed the huge, wet mess all over my counter. Apparently the water was ALSO leaking out the BOTTOM of the bowl in the middle where the blade attachment sits. So it poured all over the base unit and all over my counter.

Of course this batch of dough was completely ruined, as the yeast was dissolved into the water, which was now located all over my counter and I knew there was no way to salvage it. I was irritated. No way in the world did I expect this to happen! Can you imagine if I would've tried to double the batch from the beginning? Ugh!

After lots of reading through the instruction guide, I determined I had in fact put the pieces together correctly. Unfortunately, I then found this page:
A maximum liquid level?? I had no idea! To make matters worse, ONE cup of water actually sits above this maximum liquid level indicator. How many recipes call for less than 1 cup of liquid? When using a NINE-CUP capacity food processor??

This makes NO sense to me!

I'll be honest, this is the first time I've owned or operated a food processor. I'm new to the game. But is this common? Should I expect ALL food processors to leak if I use more than 1/2-cup of liquid in a recipe? This seems totally insane to me. Not to mention the fact that this bad boy set me back $150! I would imagine the cheaper ones to have this problem, but not this one and not a KitchenAid!

Help!!!
