I'm facing the same issue. I'm unable to remove 2 of the channels because of the following errors:
lnd: 2017-10-15 00:05:19.494 [ERR] RPCS: [closechannel] unable to close ChannelPoint(80a29b316f9eaa910b64b0e94abd09ac304a4bec0c98ceca24ea8c289816308d:0): channel with chan_id=8d301698288cea24cace980cec4b4a30ac09bd4ae9b0640b91aa9e6f319ba280 not found
and I get few of these error messages too:

I've tried removing these channels multiples times and my lightning chain has already been fully synchronized.
Force closing works internally within lnd, but it seems that we've had a regression and the confirmation dialogue (to force close) isn't currently working.
