Why i can't edit image properties on ckeditor after uploading image on laravel

i have trouble editing my image properties after uploading it in ckeditor4, the image properties seems like been disabled? i can't click anything on high and width input box, or hspace ande vspace. the only thing that i can press are the cancel and save button. does anyone have the same issue? and perhaps the solution for it?.

              CKEDITOR.replace( 'deskripsi', {                                     filebrowserUploadUrl: "", filebrowserUploadMethod: 'form',
filebrowserBrowseUrl : " type=2&editor=ckeditor&fldr=",
