Why does this hide the select in an entity browser?

This module hides the checkbox that allows for users to select an entity with the entity browser.

I have built some stuff using entity browser, I built the views and it would all be working. The only issue I have now is that this module's broswer.css file has this odd entry at the beginning.

.views-field-entity-browser-select {
  display: none;
}

Why is this here, if I comment it out then everything works well.
