Partial optimization acts strangely with Acquia Marina

Theme: acquia_marina
Optimization: Partial optimization for theme CSS development
In acquia_marina.info there is only: stylesheets[all][] = css/fusion-acquia-marina-style.css

local.css and fusion-acquia-marina-style.css are situated in the same folder (/css...), and there are more css files in that folder, but with Partial optimization for theme CSS development all files exept local.css are optimazed...

Page.tpl has code:

<?php print $styles; ?>
  <?php print $setting_styles; ?>
  <!--[if IE 8]>
  <?php print $ie8_styles; ?>
  <![endif]-->
  <!--[if IE 7]>
  <?php print $ie7_styles; ?>
  <![endif]-->
  <!--[if lte IE 6]>
  <?php print $ie6_styles; ?>
  <![endif]-->
  <?php if ($local_styles): ?>
  <?php print $local_styles; ?>
  <?php endif; ?>
  <?php print $scripts; ?>

Is it possible NO optimize css files in acquia_marina/css folder, or at least no optimize file fusion-acquia-marina-style.css from this folder?

Thanks!
