TP repeats count both transmitted and received telegrams that weren't acknowledged.
For received telegrams you can temporary enable "ACK all group telegrams" in LM KNX connection settings and see if the number of repeats changes.
For transmitted telegrams check which LM group addresses are not needed on KNX/TP side. Either disable "Write to bus" option where possible or use virtual group addresses.
You don't need to do anything to the ARP table, it's managed by the OS automatically.
