美国采购需求：电子产品，无线开关，无线开关和接收器

I recently purchased a wireless 3way switch, and I'm experiencing an issue with its functionality. One end of the switch works perfectly as expected, allowing me to control the light from that side. However, the other receiver seems to be malfunctioning, as it only turns the light on without enabling it to work as a 3way setup. Could you provide guidance on what might be causing this issue? Is there a specific troubleshooting process I should follow, or do you think it might be necessary to consider a replacement or repair? I'd appreciate any insights or recommendations you have on resolving this problem so that I can fully utilize the switch as intended. Thank you!
