Machine ID not showing when connecting by Bluetooth (IQANGo)

When connecting with IQANGo (or using remote assistance) by Bluetooth, the Machine ID is not showig in the machine list below "Select a machine..." menu. Only "Unknown", or "IQAN-G12" and a hexadecimal(?) code is showing for all machines. When there are multiple machines within Bluetooth range, this is very annoying. The Machine ID is only shown after tapping connect button. Same situation before/after pairing, or connecting to the same machine again. MD4-7 / MC43FS multi master system, IQAN G12 BT module.
