I recently upgraded to 3.0.3 and the options dropdown disappeared also. I am working on how I need to change may code to fix that.
As I mentioned in an earlier response, you can replace the connected carousel block with a text block and embed the shortcode for the connected carousel in that text block. The shortcode looks like this:
<div style="float: left; width: 100%;">[concarousel ids=752-749,747,745,746,744,743,741,731 center=true slides=5 showdescription=false captionposition=center width=100% float=left slideshow=false speed=3000 focus=false navigation=false navbar=false]</div>
As this example shows, you can mix individual items with item ranges and if you do descending item ranges the items are in descending order, ascending ranges are in ascending order. You may have also noticed that when you do individual items, they don’t have to be in ascending or descending order, just the order you want.
