Lightning: why do not balances add as much as capability?

I’ve created a model new lightning channel with two nodes.

I loaded the channel with "capability": "1000000", however "local_balance": "999056". I do know that "commit_fee": "614" accounts for some reserved sats for channel closing. However that also leaves about 330 sats unaccounted for. The place are these sats seen? Thanks
