The kickback of settlements is not computed correctly if there are multiple settlemens in one block. One example is [this transaction](https://etherscan.io/tx/0xdbd1fbdb61f4c47ffa1b9e3dae329a19d39467d33aa966826014618fae749e34). Looking at [zeromev](https://zeromev.org/block?txh=0xdbd1fbdb61f4c47ffa1b9e3dae329a19d39467d33aa966826014618fae749e34) one can see that the backrun actually belongs to [that transaction](https://etherscan.io/tx/0x9797c4713322357ae17c9336fdf4206be8bc138dbe281989f108f9f2160521ff) from the same block.
