Profile, Ender 3, Bed Centre

Hi here are my settings but I cant find any info about bed centre. Assume the switch should be on?
My Profile
(Later) Found the profile for Ender 3 onsite, but bed size is 235x235 and bed center is not zero. Can anyone comment why the bed size is larger than specified?

Also, there are no profiles for Flashforge machines; I also have the Voxelab Aquila X2, and would appreciate recommended profile settings.
Thanks for consideration. Al.
