DrugLogEdit has an uncontrolled field (null)

[RyanNerd]

react-dom.development.js:67 Warning: A component is changing an uncontrolled input to be controlled. This is likely caused by the value changing from undefined to a defined value, which should not happen. Decide between using a controlled or uncontrolled input element for the lifetime of the component. More info: https://reactjs.org/link/controlled-components

I've tried to duplicate this issue a few times but haven't found the circumstances that trigger the warning yet.
