Autocomplete Mixin with bootstrap3

[Eugen]

Hi all,
a have a layout problem with an TextField decorated with Autocomplete mixin.
The .tml:
       <t:form role="form" class="col-xs-3">
          <div class="form-group">
              <t:label for="state">State</t:label>
              <t:textfield t:id="state" value="patient.state" />
          </div>
          <div class="form-group">
             <t:label for="country">Country</t:label>
              <t:textfield t:id="country" value="patient.country"
t:mixins="autocomplete" />
          </div>
         </t:form>
The mixin is working fine, but follow layout is produced:

How can this be fixed?

Thanks
