dear experts

i noted something strange when i divide the slab membrane , when i keep the slab without dividing the moment generated is equal to Zero which is make sense in case of slab membrane , but once i divide the slab into small parts (1 X 1 ) meters the slab has been generated big moments in two direction like if you assigned the slab as a shell-thin/thick .
is there anyone faced this problem before ?
kindly see the attachments

Thank you
