Google Place Autcomplete Address API forces HTML Autocomplete = Off

We have a standard form for address (Street 1, Street 2, City, State, Zip, Country).

When I add the code for Google Places Autocomplete API on Street 1 it automatically changes the input fields autocomplete to off when loading the page which makes HTML/Browser Autofills not work on Street 1.

<input autocomplete="address-line1" type = "text" name = "shipping_address_1" id = "shipping_address_1"   class="ct-required form-control" tabindex=7>

Any ideas on how to rectify this; why would Google Place Autcomplete API change the field to autocomplete='off'?

I have tried to modify the Google javascript variable "autocomplete" to "autocomp" thinking it had something to with that but still same result.

      var placeSearch, autocomp;
  var componentForm = {
    shipping_address_1: 'short_name',
    shipping_address_2: 'long_name',
    shipping_city: 'long_name',
    shipping_state: 'short_name',
    shipping_country: 'long_name',
    shipping_zip: 'short_name'
  };



  function initAutocomplete() {
    // Create the autocomplete object, restricting the search to geographical
    // location types.
    autocomp = new google.maps.places.Autocomplete(
        /** @type {!HTMLInputElement} */(document.getElementById('shipping_address_1')),
        {
            types: ['geocode'],
            componentRestrictions: {country: "us"}
        });

    // When the user selects an address from the dropdown, populate the address
    // fields in the form.
    autocomp.addListener('place_changed', fillInAddress);
  }

  function fillInAddress() {
    // Get the place details from the autocomplete object.
    var place = autocomp.getPlace();
    //debug autofillinplaes
    console.log(place);


    for (var component in componentForm) {
      document.getElementById(component).value = '';
      document.getElementById(component).disabled = false;
    }

if (place.address_components) {
    // Get each component of the address from the place details
    // and fill the corresponding field on the form.

    var components_by_type = {};

    for (var i = 0; i < place.address_components.length; i++) {
      var addressType = place.address_components[i].types[0];
      var c = place.address_components[i];
      components_by_type[c.types[0]] = c;

    }
     var streetnumb = components_by_type['street_number'].short_name;

          var address1 = streetnumb+" "+components_by_type['route'].long_name;
            document.getElementById('shipping_address_1').value = address1;

         var locality = components_by_type['locality'].long_name;     
        document.getElementById('shipping_city').value = locality;

         var administrative_area_level_1 = components_by_type['administrative_area_level_1'].short_name;      
        document.getElementById('shipping_state').value = administrative_area_level_1;

          var country = components_by_type['country'].short_name;             
        document.getElementById('shipping_country').value = country;

          var postal_code = components_by_type['postal_code'].short_name;         
        document.getElementById('shipping_zip').value = postal_code;
