bootstrap ::before causing space issues.

I have a bootstrap modal that comes up, and the very first row in the rendered body of the modal window is  <div class=row>::before</div>.  I seem to be running into this all of a sudden, where it is hosing up the spacing on pages as well as the modal window.  The picture shows the space it creates from where white page body starts until location label, and then in the modal window the space right after the 'Close' in the modal window.

Here is rendered code as well as the code for the modal.

 <div class="modal fade " id="EntryScreen" tabindex="-1" role="dialog" aria-hidden="true">
                    <div class="modal-dialog ">
                        <div class="modal-content">
                          

                            <div class="modal-header">
                            
                                    <button type="button" class="close" data-dismiss="modal" aria-hidden="false">Close</button>

                                </div>

                            <div class="modal-body">
                                <div class="row">
                                    <div class="col-sm-2">
