W3C validator errors

I used the newest version of plugin: 1.3.2.

When I added some boxes to my website I noticed that a generated code causes some W3C validator errors.

1. Each div with id square_production_image_name_numbers contains fobidded attributes dw and dh,
2. Lines with <div entrance="1" id="square-lit" class="squareLitDemo shape" style="height: 300px; width: 300px; top: 256px; cursor: pointer; background-color: rgb(13, 35, 125);"> causes error message: Attribute entrance not allowed on element div at this point,
3. After I add more than one box on my site there is also error about duplicate div id square-lit.
