Error in Bluetooth DC 24 II

Good morning,
I would like to report an error in Bluetooth mode on new the DC 24 II. The error occurs with multiple users. The transmitter does not save the known devices ( different brands) permanently when switched off the transmitter, so when the transmiiter (bluetooth) is switched on again, you have to scroll through the entire menu to pair the headset again.
Please correct and update!

Thanks and regards

Bernhard
