thanks to @kingller 's committed : #663
the issue seem related to windows IME which confused me a lot
for guys using cleave.js via javascript, a simple patching way until fixed release maybe

var oldCleaveInit = Cleave.prototype.init;
var oldCleaveOnChange = Cleave.prototype.onChange;
Cleave.prototype.init = function() {
    var owner = this;
    oldCleaveInit.apply(this);
    owner.element.addEventListener('compositionstart', function() {
        owner.isComposition = true;
    });
    owner.element.addEventListener('compositionend', function(event) {
        owner.isComposition = false;
        owner.onChange(event);
    });
};
Cleave.prototype.onChange = function(event) {
    var owner = this;
    if (this.isComposition) {
        owner.properties.result = event.target.value;
        owner.updateValueState();
        return;
    }
    oldCleaveOnChange.apply(this, [event]);
};

I modify onChange event with below code and work well, maybe this help someone.
(as using zh-TW input method and numeric keypad)

Cleave.prototype.onChange = function(event) {
  const owner = this
  if (owner.isComposition && event.inputType === 'insertCompositionText') return
  oldCleaveOnChange.apply(this, [event])
}
