can't save metadata for 16 bit Grayscale TIFF

[dimi_0277]

Hello, I have several 16bit TIFF Grayscale files (black/white negative scans), and as soon as I do some edit on them with the Develop panel, the "metadata is changed" flag pops up and if I save the metadata to file, or if I choose to read the metadata from file, the flag doesn't disappear. Only way to make it disappear is by resetting the edits I've done. If I convert the files to RGB, the issue is gone and everything is fine.

Of course I also tried that on a new/fresh catalog, and it does the same. Is there any way to fix this without converting all my Grayscale files to RGB? It would be a huge waste of disk space,

thank you

Ignore that flag. It does not serve any purpose unless you routinely write metadata to files for some specific reason. You can turn it off completely in 'View Options'.

thanks, but yes I routinely write and edit metadata (the main purpose I use Lightroom is to catalog my photos, not much for editing), so it is pretty annoying, I hope there is a fix
