TCP_IP_W5500 Flush data

[RGV250]

Hi,
I am playing with the ARP_01 file and have an issue I cannot work out. It works to a point but I am also getting data that is incorrect (to be honest I have not checked all the data anyway yet).
The scan goes through but if you look at the txt file, when it gets to address 9 (which does not exist) it shows address 6 duplicated. Then when it gets to 15 it shows 13 duplicated, 13 does exist so it should have showed that.
The only thing I can think of is that "Flush data" command is not working correctly. I tried clearing Rx_IP[0..3] but this does not work so it is not residual data here.
