I am trying the ble_app_gls example of nRF SDK v16.0 on nRF52 DK device. The only modification is change s132 to s112.
After download the app to nRF52 device, I can successfully bond to the GLS sample peripheral from the "nRF Connect" app on my Android phone. A 6 digit password was shown on RTT log terminal and I entered on phone side during bonding.
I then deleted the bonding from central side (via phone bluetooth settings) but not from the peripheral. Then from the phone side, I found that I can never bond to the device again, the RTT log terminal shows the following

From the log we can tell that the peripheral still keeps the peer central, but it kept rejecting the central's bonding request.
Is this behavior by design?
