Form validation with Multiselect

Validation Error message is not getting reset after selecting the options from the multiselect              Steps to produce :    1)  submit the form without filling any detail.   2) It will display Validation Error message for required existing fields.   3) select a value in a multiselect field       Expected Behavior:  Validation Error message should be removed from particular field  current Behavior: Validation Error message not getting removed   I am trying to call a microflow in “on change” event which is causing removing/resetting all Validation Error messages in other field as well. It should remove/reset only those multiselect fields which value has been changed.

This behaviour can only be achieved with custom validation setup. The out-of-the-box validation only changes with a full submit of the form.
