Lightroom Classic 7.5: Black and White and HSL Mix settings not preserved across Treatment changes

Throughout the process of working on images, I frequently must switch Treatment modes back and forth from Black and White to Color. In Lightroom Classic CC 7.5, the channel mixing panel no longer preserves the opposite treatment's settings when switching between treatments.

The issue can be replicated by changing the Treatment to Black & White, altering the mix settings in the B&W panel, then toggling the treatment to Color and back again. The black and white mix settings will have been reset. The same holds for the opposite — working in Color, then changing to black and white and back again.

This completely foils workflows in which one must toggle back and forth between modes in order to refine mix settings (e.g. assessing the image in color, switching to b&w to make changes, and so on). As a photographer who must often produce both color and b&w images, I have traditionally kept both versions in the same file in order to consolidate my library a bit. This problem prevents me from doing so, meaning I would need to go back and reproduce years-old edits on tens of thousands of files if that data has been lost.

I am not familiar with how version 7.5 handles the metadata of edit histories or whether it differs from prior versions of Lightroom, but I expect that many photographers' livelihoods (and sentiments) would be saved if this problem were reversible without losing the information that previous versions of Lightroom Classic kept intact.

I bug reported it 6 months ago, Rikk (ref 4197763). I've even recorded a Hitler rant video, which you may have seen. It's amazing that this hasn't been fixed.

I just updated to Lightroom Classic CC 8.2 and it looks like the issue is mostly fixed — changes to the B&W mix settings are indeed now preserved when toggling back and forth between treatment modes.

However, when I apply the "Auto" black and white mix, the automatic mix settings are not preserved across changes in the treatment mode, unless I manually change any of the sliders' values before switching treatment modes.

So the current solution seems to be an incomplete one, but the major edge case is an easy one to remember. It looks like I will at least be able to remain on the current version of Lightroom — thank you for helping to file a bug report for the issue.
