Hi Pat, No they aren't in series. Check this picture to get the idea:
This means both the wm8805 and the USB receiver get a 47R resistor each. For the timebeing you have two options:
1. Leave the 110R resistor in place and solder two pieces of solid wire instead of the 47R resistors (see pic below). Now your Chameleon is still fully functioning (both USB and S/PDIF) though you will have reflections between the receiverchips.
2. Remove your 110R resistor and put a peace of solid wire instead and place the 110R resistor on the spots of one of the 47R resistors. The top resistor (leg 3&4) is leading to the SP/DIF receiver, the bottem resistor (leg 10&11) is leading to the USB receiver. Now you won't have reflections but either one of the two inputs will work.
