I use a carolina rig on one and a high low rig w only a low rig on the other just high enough to suspend the bait off the bottom. Some days one will rule and you can switch all your poles to that setup. If theres grass on the bottom the low rig will prob win but not always. My other thought was that you may be seeing grass carp as opposed to common carp or the carp just aren't eating off the bottom. I have a reservior by my house that has billions of carp that we catch all the time but some days you can see 20 floating around over your bait and they just wont eat that day. Mulberries are incredible for commons but I once read about natural cravings and sometimes they want oil and fat and sometimes their bodies want sugars etc. so cover two food groups and you should better your chances. Your setup sounds perfect, try somewhere else on that lake or another.
