Just found this thread. I've been having the same problem on 6.9.2, in that I cannot change the custom temperature thresholds for my three NVMe drives.
When I went to look at /boot/config/smart-one.cfg, it was actually empty. A zero-byte file. What I ended up doing was editing it and adding a space character and saving it, so that it wasn't totally empty.
Once I did that, updating the temperatures from the GUI now works properly. No need for manual editing.

Something to try if you're seeing the same thing.
