Cannot select multiple images when pressing enter

[tuanta1992]

window.CKFinder.modal({
chooseFiles: true,
width: 800,
height: 600,
onInit: function (finder) {
finder.on('files:choose', function (evt) {
var files = evt.data.files;
console.log(files);
})
})
});
When I select multiple images and start clicking the select button, the system returns the array of selected images, but when I select multiple images and press the enter button, only one image is returned, why? I don't remember this problem on ckfinder 2.
