Unity keeps baking the light map

Anybody knows why when i have auto generate unchecked, unity goes ahead and constantly bake the light anyway using 100% of the CPU during that time and it keeps doing that even when Im still editing the scene it constantly keeps baking.

Even if i exit unity to force it to stop, when i start it again its determined to keep baking even when auto generate is unchecked..

I thought the auto generate check box is there to prevent that?

im using unity 2021.2.17f1

You would think this would have been fixed by the year 2020? I can easily write the code for that, let me help out the unity engineers, this is how you do it guys......

if (autoGenerate is checked) {
waste_100%_cpu_generating_light_map();
}

I have such an extreme urge to switch to Unreal engine, unity is hell bent in using 100% of the CPU,GPU, hard drive space and anything else you got on there 100% of the time, even if you are doing nothing the CPU is at 100%. they have a real need for speed it seems.
