You must use a different Receiver Number for each different AFHDS 2A receiver you bind. Re-using numbers will remove the binding for the previous receiver.
A maximum of 64 AFHDS 2A receivers can be bound to the MULTI-Module.
If telemetry data is incomplete (for example, missing receiver RSSI) you need to upgrade your RX firmware to version 1.6 or later. You can do it from an original FlySky radio, or using an ST-Link programmer, as explained in this tutorial.
