When OTA and bonding both features are enabled, the bond information gets erased from flash each time I disconnect from the device. Any suggestions on this?

I am using BLE Chat application where I have added the bonding feature. When I don't use OTA, I can connect to the device and bond it and the bond information stays even after reconnecting to the device.

But when the OTA is enabled, once I connect to the device and bond it and disconnect it the bond information is getting erased and the device is again asking to bond on reconnection.
