Should be something easy to fix.
Checking the onchange, the value is set to null, when it should be set to undefined.

Just remove getValueProps from the Form.Item.

I am having this too. Any plan to fix this?
All the other form items get set to undefined when cleared, why's this one different?
We need it undefined to differentiate when we send null on purpose. Thanks!
