Overlapping of label and value on input text box in materialize in ember

i have installed materialize plugin in my ember app using ‘bower install materialize’

i have created a form in my hbs–

> <div class="input-field col s12 m12 l8">
>               <i class="material-icons prefix">email</i>
>               {{input id="email" type="text" name="email" class="validate" value="overlap"}}
>               <label for="email">Email<i class="mandatoryIcon">*</i></label>
>             </div>

but in ui this label and value are getting overlapped. need to fix this issue… how to do ???
