LND channel in limbo even though it's way past its maturation block height

Hi all,

What could explain this?:


What I have is a “Closing” channel with the following output from sudo docker exec -it lightning_lnd_1 lncli pendingchannels:

{
    "total_limbo_balance":  "2xxxxxx",
    "pending_open_channels":  [],
    "pending_closing_channels":  [],

        {
