2 Chroma light strip argb controler, only one show on Synapse 3

I purchased 2 chroma light streap sets to make my ideal . The first have to control : Port 1 :1 light strip of 120 leds Port 2 :1 light strip of 30 leds Port 3 :1 light strip of 60 leds The second have to control : Port 1 :1 light strip of 60 leds Port 2 :1 light strip of 60 leds But only the first controler appear in synapse 3. (if I turn off the first controler and unplug/replug the dongle, then the 2nd controler show up). How can i make both to show up on Synapse 3 ? Thanks in advance :)
