Mining with a GTX 690 problem??

Hey guys, as most know the GTX 690 is a 2 chip graphics card, so on my secondary computer (my gf's) I have a GTX Titan and two GTX 690's in there. I'm mining BTG with them right now and when I start the EWBF Miner it seems like it detects two chips on a 690 and only one on the other, when I start EWBF it looks like this:

GPU0: GTX Titan
GPU1: GTX 690
GPU2: GTX 690
GPU3: GTX 690

Now, I'm assuming its picking up both chips out of one card and only one chip on the other??? Just wondering if anyone has mined with these before and if they've ever experienced this or if you guys have any input! Thanks guys! It's pretty sweet I work at a computer repair shop and I did a custom loop for cpu/gpu for a customer and when he came and picked it up he said to me "Hey I got a few computers in the basement with some graphics cards in them, they're a little old but you want to just come buy and take it?" I said hell yeah and when I showed up I seen two complete builds waiting for me to take (yeah they were dusty but who cares?!) first build had an ASUS Rampage Extreme IV Black Edition Motherboard, i7 4930k, 32 GB (4GBx8) Corsair Dominator RAM, GTX Titan, Corsair AX1200i PSU(I was really most excited about these, theyre freaking $350 a piece!) 1 TB Samsung 840 Evo SSD, few 2TB HDD's and the second build had an ASUS Rampage Extreme IV Motherboard, i7 3930k, 32GB (8GBx4) Corsair Vengeance RAM, 2 GTX 690's, another AX1200i PSU (freaking love those hahah), a Corsair 240GB SSD and anothher few 1TB HDD's..... I was like FUCK YEAH LETS GO!@#!@# Hahaha so after not really deciding on what to do with it all I used the best and built my GF a computer and now I have a i7 3930k build which I really don't know what to do with yet, undecided still lol. Anyway completely off topic now haha. So back to my original question, since the 690 has 2 chips and the EWBF miner indeed displays 3 690's detected, shouldn't there be 4??? Thanks guys!!!!
