When the internal scroll bar feature for form sections is enabled, the Save button in each section will be hidden.
To show the Save button in each section, the internal scroll bar feature can be disabled in Provisioning > Company Settings > Disable the internal scroll bar next to forms.
Firefox or Chrome will never show the scroll bar for form sections even if this feature is turned on. That is why in Firefox or Chrome the Save button in each section is always shown.
Other browsers may behave similar to Firefox and Chrome.
