Tools / Options / Disk Space always resets to 350MB after restart

I'm new to Thunderbird & have just set up V. 57.2.0 (Windows). I'd like to reduce the amount of space allocated to the Cache, but if I modify the figure at Tools / Options / Disk Space, it always resets to the default 350MB after restarting the application. In other words my modified setting doesn't 'stick'. Could this be a minor bug, or am I doing something wrong??

my pre-release version has an option to over ride automatic cache management. My guess is you need that you need that and it has not been implemented in the release version as yet. But I was not successful in locating a bug to explain the change.
