file upload doc docx not accepted

I am using Perch Forms and can successfully upload pdf's. These are going to a folder outside of my root. I get the perch:error "file type not accepted" message when uploading files with extension doc or docx. At one time I also had extension .doc and .docx in my "accept" tag, but upload was still not accepted.
This is from my dev site, but am encountering the same pdf success but doc docx failure on my staging server.

Template:

                <div class="larger_label">
                        <perch:label for="sendfile">Send us a file</perch:label>
                    <perch:input type="file" id="sendfile" accept="pdf doc docx xls xlsx txt" />
                        <perch:error for="sendfile" type="filetype"><span class="error">File type is not accepted.</span>
                        </perch:error>
                </div>

Here's line 21 from the core/inc/apps file:

<?php
    $apps_list = array();
    include(PERCH_PATH . '/config/apps.php');

    if (PerchUtil::count($apps_list)) {
        foreach($apps_list as $app_id) {
            switch($app_id) {
                case 'content':
                    include(PERCH_PATH.'/core/apps/content/runtime.php');
                    break;

                case 'assets':
                    include(PERCH_PATH.'/core/apps/assets/runtime.php');
                    break;

                case 'categories':
                    include(PERCH_PATH.'/core/apps/categories/runtime.php');
                    break;

                default:
                    if (!include(PERCH_PATH.'/addons/apps/'.$app_id.'/runtime.php')) {
                        PerchUtil::debug('Your config/apps.php contains "'.$app_id.'" but that app is not installed.', 'error');
                    }
                    break;
            }
        }
    }

The mime types seem from filetypes.ini seem right:

[office] 
application/arj
application/excel
application/mspowerpoint
application/msword

...

application/vnd.openxmlformats-officedocument.wordprocessingml.document
application/vnd.openxmlformats-officedocument.wordprocessingml.template
application/wordperfect
application/x-excel
application/x-msexcel

I'm not sure what I am doing wrong. Thoughts? Thank you!
