LIGHTNING LND failed to load config: lnd.conf: unknown option: logdir?

In my lnd.conf:

logdir=Z:\LND\logs

logdir is a valid option according to:
sample-lnd.conf

but I get:

Z:\LND> .\lnd --configfile=Z:\LND\lnd.conf
failed to load config: Z:\LND\lnd.conf:55: unknown option: logdir

I am running LND lnd-windows-amd64-v0.14.2-beta on Windows 10.
I get this error w/ other valid .conf options too.

When I comment out the offending option, LND launches as expected:

Z:\LND> .\lnd --configfile=Z:\LND\lnd.conf
