Why is layout floating in zen, drupal?

Question

Drupal

Got a theme that needs to be made adaptive. I edit via scss.
I have the following:

* The layout when there is only one sidebar, the right one.
   */
  .sidebar-second {
    /* Span 4 columns, starting in 1st column from left. */
    #content {
      @include zen-grid-item(4, 1);
    }

    /* Span 1 column, starting in 5th column from left. */
    .region-sidebar-second {
      @include zen-grid-item(1, 5);
    }
  }

After compas watch I get this:

.sidebar-second #content {
  float: left;
  width: 400%;
  margin-left: 0%;
  margin-right: -400%;

.sidebar-second .region-sidebar-second {
  float: left;
  width: 100%;
  margin-left: 400%;
  margin-right: -500%;

Although I suspect it should be:

.sidebar-second #content {
  float: left;
  width: 80%;
  margin-left: 0%;
  margin-right: -80%;

.sidebar-second .region-sidebar-second {
  float: left;
  width: 20%;
  margin-left: 80%;
  margin-right: -100%;

What went wrong and where? put a clean theme (drush zen) and after processing the compass the same turbidity.
Is something not connected? maybe you need to add something?
Thanks in advance for your replies!
