Try putting a lot of lubricant on the side of the silicone rings that touches your skin.... I think the silicone rings are sticking to you skin and as your breasts are being pulled into the domes the rings come along for the ride! allowing your skin to slide more easily over the silicone should fix it... you could even try using a silicone based anti chaffing gel like Monistat...
