• Notice in the UI, the Process tabs with modifications are orange, indicating settings are modified
• Change to another process tab

Anything else?

I included the debug log (nothing useful), the original project file, and a screen capture showing the behavior. Same behavior occurs on Windows nightly. There is a similar issue reported in 2023 but the referenced link to the fix is dead.

Can confirm, after transfer all the settings are lost.
