I built 6.14 while configuring with --enable-lzo

Configure says:
	zstd support:       no
	lzo support:        yes

Finally running mkfs.btrfs with --compress lzo

I get:
-EXPERIMENTAL -INJECT -STATIC -LZO -ZSTD -UDEV +FSVERITY -ZONED 
CRYPTO=builtin

And
ERROR: lzo support not compiled in

Strangely: when I run with --compress zlib and I check the resulting 
image with btrfs-compsize it says:

Processed 8969984 files, 2574779 regular extents (6008702 refs), 5007593

Seems like it tries lzo anyway and is mixed up about support not built in.
