After a Field get submitError, how to reset it ?

i'm not good at english. Thank you for your understanding..
the problem is after i submit a Form,
Field will get meta.submitError then it's forever not changed.
meta.submitError is forever..

how to submitError to be cleared when field is touched or blured??

i can't find a way to initiate a specific Field.
of course form.reset() is clear, but i wan't to know just reset one specific field.
