If you already changed it, please change to "Default is the size of the 2 last sectors of internal flash".

I dont think size can be 0 here because its Non default configuration and here start_address==0, so size must be different.
If for any reason size is 0 , then when you calculate above:
start_address = flash_end_address - size;
aligned_start_address = align_down(start_address, flash.get_sector_size(start_address));
start_address will become flash_end_address and then
I think it should be flash.get_sector_size(start_address-1)
…efault values are use remove of rbp_number_of_entries from the kvstore configuration. Adding default option for storage_type allowing the system to choose TDB_INTERNAl, TDB_EXTERNAL or FILESYSTEM base on the blockdevice component set in the target board. Adding remarks to kv_config.cpp and break simplify the _get_blockdevice_FLASHIAP function

Description
The function _get_blockdevice_FLASHIAP in kv_config.cpp has been refactored into 3 function. the first function will calculate the default start address and size for internal TDBStore in case of rbp when KVStore is configured as TDB_EXTERNAL or FILESYSTEM. a second function will calculate the default start address and size for the case we run in TDB_INTERNAL. and the last is _get_blockdevice_FLASHIAP which will check the validity of parameters and create the block device.
Also, lots of remarks have been added to the code in order to simplify the understanding of the complex configuration code.
Last thing, the parameter of rbp_num_of_enteries has been remove from TDB_EXTERNAl and FILESYSTEM configuration files.
