@SilenceOfNight NoForm's empty/invalid value is 'null' instead of undefined because we believe that 'null' is something you know it is empty for sure, but 'undefined' isn't.

And it is also need to point out that reset means make all fields null instead of so called initial values.

I recommand that you can save your initial values and reset values by this way:

const initialValues = { ... };
this.core.setValues(initialValues)
