maxTotalFileSize option parameter being triggered, due to template size problem

[alexdshark]

STATEMENT:
maxFileSize set to 1 MB
maxTotalFileSize set to 2 MB
The file (file1) being mock-up in template is 100kb (specified in template size) shows gray template displayed. [found workaround by making it negative]
Now, when you load a 2nd real file, way less than 500kb, you get that maxTotalFileSize has been exceed it. It appear that their is something wrong with template size counter.

HTML:

INFO: filename & filesize are attributes being access to reference in template of file1

    <div class="form-group">
        <button type="submit" class="btn btn-md  d-block mx-auto" style="color: black; background-color: #68FFDE; z-index: 10;"> Submit </button>
        <input type="hidden" id="homeworkid" name="homeworkid" value="<?= $row['homeworkid'] ?>">
        <input type="hidden" id="file1" name="file1" class="<?= $file1exists ?>" filename="<?= $row['file1name'] ?>" filesize="<?= $row['file1size'] ?>" value="">            
    </div>

JAVASCRIPT:
var inputElement = document.querySelector('#homeworkForm input[type="file"]');

// Create the FilePond instance
if ( typeof pond !== 'undefined' )  pond.destroy();
var pond = FilePond.create(inputElement, {

                    }

Please correctly format our code snippets.

I'm note sure what you mean with "template".

Can you please create a test case on codesandbox.io, you can use this example as a starting point: https://codesandbox.io/s/vanilla-filepond-2oltb
