Devices: Samsung A52S

Hi I got a strange case trying to bonding a device. When I select a device from scanner, a Pairing dialog appears. When dialog appears twice, I got the device paired and I can see it in Bluetooth Settings as Bonded. But when the Pairing dialogs appears only once, I receive data but the device disappears from Settings and also from Scan. If I want that device appears again I have to reset the NDK.
I attach a video demo in which you can see that the device AIHBAND (which is the name of the NDK) disappears and I can connect again when the pairing dialog appears just once.

Also you can find the logs here:

We also encounter double pairing popups. I don't understand the root cause. A far as I know, some method is called twice on the firmware side causing this issue, but I don't know which one. Please, ask on https://devzone.nordicsemi.com.
